Catalyst Swing Count:
495
32 inches, 25 ounces
This is a conservative estimate based on 6 batters batting 4 times and connecting two times per at bat in each game and 150 initial break-in swings.
Around 300 hits, the bat started launching balls and the team scored 23 runs in 3 innings before the game was called.
At some point, the bat will go dead and it'll be good data knowing how long this type truly lasts.
Update 9/29/08 Still hitting well halfway into season 5. We'll estimate 5 batters have used it for 4 games, 3 times per game with 2 pitches per at bat with one set of hands: 5 x 4 x 3 x 2 x 1 = 120 swings to be added to 375 = 495.
