737 Cargo unload/load times

Hey everyone

Question concerning the 738:
In my case the Taxi and Cargo times are defining the turnaround times and so far I use the 736 and 73G.
736 cargo load/unload on a Class 10 airport is 37 minutes
73G needs 48 minutes
This is approximately the maximum cargo divided by 100. So before leasing a 738, is this just a coincidence or will the 738 really have a cargo unload/load time of 76 minutes?

I’m using the 738 and (when I transport 44 CU) I have a 47min turnaround flying from 10bar to 10bar.
