Alright... Then a Monk/Fighter 5, Monk/Shintao Monk 10, Monk/Henshin Monk 5 has a total of 35 levels of Monk stacking abilities? So he's moving at level 13 he's moving at 100 FT/round, with a +4 AC bonus, and all of the other fancy abilities of a monk... Oh, he also maxes out past the Epic Monk's listing here.. 1/5 monk level or equivalent... +10/3 levels on the Epic board...
So your Monk has 140 ft/round move, +7 to his AC... Oh, and he also has some rather gnarly bits for his powers from Shintao and Henshin. Of course he also has +16 BAB and tops out the old Monk Combat charts for unarmed attacks, though if you follow the chart +13/10/7/4/1 for his additional attacks for being Monk awesome... Not including all the goodies from the two monk classes.
The intention of the rule as you quote it allows any class that stacks levels to produce 35 levels worth of 'stacking' (as long as you can enter into a qualifying PrC by level 5 which is... Definitely possible).
Slainte,
