You have a good point, but you are unfortunately basing it on the assumptions that:
#1: Rabbits and turtles warp in the same way.
#2: All warps are created equal, which we know not to be true already by looking at JJ1.
When you consider that Devan's warp machine is activated whenever he needs it to be, it only makes sense that the warp might be more advanced, or at least automatically make sure that it comes out on solid ground.
And I'm pretty sure Devan takes 200 hits, not 100.
