I'm going to another prop shop and get a second opinion

What is really strange is the massive deviation that you are getting. If you were consistantly getting 270s, then we could assume your speed had dropped substanitally. And with a 5# drop, 30fps is more than normal... even 20 would be a bit high. The fact that the chrono would give you 270s, then290s and then more 270s suggests a couple of things to me...

1) chrono isjacked up

2) Lights effecting chrono

3) You are creeping the bow (REAL BAD!)

4) You may not be shooting squarely through the chrono.

Just suggestions. They are machines..and they canfail like anything else.

I think you have a bad chrono. A drop of 5 pounds in draw weight should only drop your speed approximately 10 feet per second.
