Minor maintenance problem

Yesterday I received a 737-900ER BGW, I transferred all the flights I had assigned to a 737-700 BGW which was running with a maintenance ratio of 102% and had a maintenance ratio on the 900 of 96% does the 900 then require marginally more time the the 700 to recoup maintenance points? I’d assumed that because the turn around time and maintenance category were the same the resulting maintenance time would be the same.
