I agree -- the vests are a crutch for the weak and should not be used. HTFU.

Well, chyeah! Especially if all they're shooting is 9mm ball. That doesn't even hurt that much.

rhino out!

Is...is that english? or are you referencing some sci-fi fake math joke?

Back in 1983-1989, my life would have been better if it was just a sci-fi fake math joke!

The equation I posted is essentially an application of Newton's 2nd Law to fluid flows, i.e. it represents a set of three equations that govern the transfer of momentum in fluids. The form I posted was for incompressible fluids (liquids). It's a bit more complicated for compressible fluids (gases). In practice, it's often possible to simplify the system of equations dramatically based on known information and a more convenient solution emerges. Knowing how to apply given information and assumption to simplify sufficiently for a solution is a huge part of studying fluid dynamics.

This is what I ponder when I am shooting, which explains why my times are so slow in USPSA.
