Opinion of the Court
COX, Judge:1. Appellant was tried by general court-martial, military judge sitting alone, at Keesler Air Force Base, Mississippi. Pursuant to his pleas, appellant was found guilty of uttering bad cheeks with intent to defraud (2 specifications), wrongfully uttering a bad check for a past due obligation, and wrongful appropriation, in violation of Articles 123a and 121, Uniform Code of Military Justice, 10 USC §§ 923a and 921, respectively. Appellant was sentenced to a bad-conduct discharge, confinement and forfeiture of $350 pay per month for 28 months, and reduction to the lowest enlisted grade. The convening authority approved the sentence, and the Court of Military Review1 affirmed the findings and sentence in an unpublished opinion on March 10, 1993. 1993 WL 76298.
*3772. We granted review of the following issues:2
I
WHETHER THE AIR FORCE COURT OF MILITARY REVIEW COMMITTED REVERSIBLE ERROR WHEN IT DISREGARDED THE CLEAR LANGUAGE OF R.C.M. 307(c)(4), UCMJ AND THIS COURT’S LEARNED OPINION IN UNITED STATES V. POOLE, 26 MJ 272 (1988), AND UNITED STATES V DAVIS, [16 USCMA 207,] 36 CMR 363 (1966) WHICH RECOGNIZED THE RULE THAT EACH SPECIFICATION CONTAIN ONE OFFENSE AND THE MAXIMUM PUNISHMENT IS DETERMINED BY THE AMOUNT OF THE LARGEST SINGLE CHECK.
II
WHETHER APPELLANT’S PLEAS WERE IMPROVIDENT DUE TO ERRONEOUS INFORMATION BEING GIVEN TO APPELLANT CONCERNING THE MAXIMUM PUNISHMENT AUTHORIZED.
3. We hold that the pleas of guilty were provident; however, we decline to adopt the methodology employed by the Air Force Court in calculating the punishment. We also hold that the military judge miscalculated the possible maximum punishment but that his calculation did not prejudice the rights of appellant, Art. 59(a), UCMJ, 10 USC § 859(a), because the maximum punishment determined by the military judge is less than the maximum punishment authorized by the Manual for Courts-Martial, United States, 1984, except for the character of the punitive discharge. Accordingly, the granted issues are without merit.

4. Appellant uttered a total of 18.bad checks and was also convicted of wrongful appropriation of property of a value greater than $100. The bad-check offenses in Charge I were charged as follows: 10 checks, each with a face value of $100 under specification 1; 7 checks with values under $100 under specification 2. The last bad check, valued at $546.75 as payment for a just debt, was charged in Additional Charge I. The military judge advised appellant that the maximum punishment for his offenses included confinement for 6-1/2 years and then ascertained that both counsel were satisfied that this calculation accurately reflected the maximum punishment allowable. The 6—1/2— year figure was presumably reached in the following manner:3
Specification 1, Charge I: Aggregation of 10 checks, totaling $1000 = 5 years;
Specification 2, Charge I: Aggregation of 7 checks, totaling $240 = 6 months; Additional Charge I: One bad check as payment for overdue debt = 6 months; Additional Charge II: Wrongful appropriation of a value greater than $100 = 6 months.
See paras. 49(e)(1) and (2), and 46 e(2), Part IV, Manual, supra.
5. In this case, appellant signed a pretrial agreement limiting confinement to 3-1/4 years (39 months), with the understanding that the maximum punishment allowable for his offenses included dishonorable discharge and confinement for up to 6-1/2 years. Focusing on specification 1, appellant now argues the maximum confinement should have been calculated as 2 years, not 6-1/2, and discharge should have been limited to a bad-conduct discharge. This argument is based upon the decision of the United States Army Court of Military Review in United States v. Poole, 24 MJ 539 (1987), aff'd, 26 MJ 272 (CMA 1988), which would limit the maximum punishment for specifications 1 and 2 of *378Charge I, as worded, to 6 months per specification because neither specification alleged a check of a value greater than $100. The Army court calculated the maximum punishment in a duplicitous specification as being the maximum punishment authorized for the largest single check. Furthermore, as appellant has correctly argued, the punitive discharge would be limited to a bad-conduct discharge if no check exceeded $100.00. See para. 49e(l)(a), Part IV, Manual, supra.

6. Our decision to uphold the guilty pleas is founded upon the following rationale. First, while charges and specifications alleging all known offenses by an accused may be preferred at the same time, RCM 307(c)(4), Manual, supra, establishes: “Each specification shall state only one offense.” Thus, these specifications are duplicitous.
7. Second, appellant did not object to the misjoinder of numerous bad-check offenses into one duplicitous specification; thus he waived any complaint that he may now have about the pleadings. See RCM 905(b)(2) and (e).
8. Third, RCM 1003(c)(l)(A)(i) authorizes punishment “for each separate offense, not for each specification.” We look to the offenses of which an accused has been convicted to determine his punishment. Notwithstanding the joinder of multiple offenses under each specification in Charge I, in reality appellant was convicted of 17 offenses of uttering bad checks, in violation of Article 123a. The maximum punishment for each of the charged offenses was a bad-conduct discharge, 6 months’ confinement, total forfeitures, and reduction to the lowest enlisted grade. In the aggregate, he thus could have been sentenced to 102 months of confinement for these check offenses (plus additional punishment for the other offenses).
9. Lastly, in this case we have not looked beyond bad-check offenses. We neither condone nor condemn the practice of joining numerous offenses into one specification for ease of pleading and prosecuting the case. We now only hold that in bad-check cases, the maximum punishment is calculated by the number and amount of the checks as if they had been charged separately, regardless whether the Government correctly pleads only one offense in each specification or whether the Government joins them in a single specification as they have here. We can find no prejudice to an accused in this circumstance.

10. We are then left with deciding whether the misadvice as to the nature of the discharge rendered the plea improvident. “A plea of guilty may be improvident because it is predicated upon a substantial misunderstanding on the accused’s part of the maximum punishment to which he is subject.” See United States v. Poole, 26 MJ at 274; United States v. Hunt, 10 MJ 222, 223 (CMA 1981); United States v. Castrillon-Moreno, 7 MJ 414, 415 (CMA 1979). Although we have “rejected a mathematical formula” to determine what misunderstanding amounts to a “substantial misunderstanding,” United States v. Hemingway, 36 MJ 349, 352, 353 (CMA 1993), we will take into consideration “all the circumstances of the case ... to determine whether the misapprehension of the maximum sentence affected the guilty plea, or whether that factor was insubstantial in [appellant’s] decision to plead” guilty. Id. at 353; United States v. Walker, 34 MJ 264, 266 (CMA 1992); United States v. Hunt, 10 MJ at 223-24; United States v. Walls, 9 MJ 88 (CMA 1980).
11. Because the maximum potential confinement was actually greater than appellant was led to believe and because appellant only received a bad-conduct discharge, he obviously was not prejudiced by the military judge’s ruling.
The decision of the United States Air Force Court of Military Review is affirmed.

. The granted issue is as stated in the Supplement unless stated differently in the Grant Order. Counsel do not have license to paraphrase or revise it on their own.
. This calculation was reached during a conference convened under RCM 802, Manual for Courts-Martial, United States, 1984, not on record. Therefore, we have no information other than that suggested in the Government’s brief regarding exactly how the maximum was set.
