Our Standard Heated Bat Rolling Service includes a compression test of the bat right away so we have a reference point of the current stiffness. A compression tester is a device with a gauge on it. The bat is placed in the tester to determine the current break in state. We then put it through the process described above until the bat is within 15-25 psi on the appropriate gauge. When pushing the bats to this mark, it ensures the bat is through its dead phase and is performing right up to the max factory guidelines and still on the passing side of a compression test when they arrive. This standard service will deliver a game ready bat and continue to break in naturally.
Our ProMax Performance Heated Bat Rolling Service includes all the services above but we proceed to push the bat to the upper levels of performance past the passing specs on the appropriate gauge. When we do this the bat will perform at its ultimate performance and will not pass a compression test if performed on the bat. A bat that does not pass a compression test would not be allowed to be used in that specific event. This service does take nearly twice as long as we do need to test the bat multiple times throughout the process to ensure it is broken in without breaking it, it is a fine line with delicate testing instruments. When your bat comes back with this service performed it should only be used in home run derbies and showcase events as it does not comply to any sanction rules. It will also be a firestick like you have not swung before.
