This past Sunday, I competed in a very well-run USAS RFP PTO at Chabot Gun Club in Castro Valley, CA, that was held on stationary targets with a $130 shot timer. This is completely legal within USAS rules (see Sect. 6.3.17B).
(A shout-out to Rudy S. and David G., who made it all possible.)
This was the real deal. I've competed in RF matches throughout the world, and the local club stacks up. (To wit: sadly, I lost a shot due to a double malfunction, and ate another 10 [possible] points due to being 0.05s late on a 6s string.)

Yes, Virginia, that man is shooting a High Standard.

Folks, rapid fire really is as simple as this:

(50-foot reduced targets)
and this:

Given the above, I can't picture a gun club that I've belonged to where you couldn't staple up 5 targets, grab a shot timer, and run an international rapid fire match.
So start it at your club!
ETA: 0.05s rather than 0.15s; it helps to read the rule book.
