How’s the move from 24/28 to 48/96?

My department is on a 24/48 with a Kelly day (12 hrs off) every 27 days. We get paid biweekly and have three different paychecks they are the 103, 113, and the 120. How do the pay systems work for this schedule? I’m afraid of it because someone told me the paychecks would be 48, 96, and 144 I don’t see how someone can realistically budget for that kind of schedule without the finance department trying to find an average of the 3 pay checks to pay us biweekly.
