Assuming:
110% BE
12 peasants per acre at 1200 acres = 14400 peasants
30% income sci
10000 troops

38% banks vs 30% banks 8% arms

30% banks: 360
38% banks: 456

Raw Income (30% banks): 14400*2 + 360*25*1.1 = 38700
Raw Income (38% banks): 14400*2 + 456*25*1.1 = 41340

Bank bonus (30% banks): .3 * 1.1 * .7 = 23.1%
Bank bonus (38% banks): .38 * 1.1 * .62 = 25% (capped)

Mod Income (30% banks): 38700 * 1.3(human) *1.3(sci) *1.231(banks) * 1.04(baron) = 83731
Mod Income (38% banks): 41340 * 1.3 * 1.3 * 1.25 * 1.04(baron) = 90823

Wages (0 armouries): 10000*.5*.85(inspire army)=4250
Wages (8% armouries): 10000*.5*.85(ia)*.84arms)=3570

Total income(0 arms): 86573
Total income(8 arms): 80161

Cost per elite (0 arms): 900gc
Cost per elite (8 arms): 900 * .88 = 792

Time to train 6500 elites(0 arms): 6500*900/86573 = 68h
Time to train 6500 elites(8 arms): 6500*792/80161 = 64h
