Instructions for use of the G4 baseball bat tester.
The lowest passing scores for each type of bat using the G4 will be as follows:

Metal bats: 1250 psi

Composite bats: 1000 psi

Non-linear (i.e., based on March 17, 2017 letter from NCAA indicating that the bat
passes BBCOR at a lower psi level than typical)

Rawlings Quattro (composite)
800 psi

A test will be considered passed or failed as follows:
If the bat meets or exceeds the passing score threshold on the first test, it will be
considered to have passed testing.

If the bat does not meet the passing score threshold on the first test, it will be
rotated 90 degrees (either direction) and tested again. If the bat meets or exceeds
the passing score threshold on the second test, it will be considered to have passed
testing. If the bat fails to meet the passing score threshold on the second test, the
bat will be considered to have failed testing.
