That calculation is probably closer than mine---I simplify by assuming 648 Plate appearances a year (which is a bit low unless batting down in lineup)
648 is simple because it is 3 times the 216 possible rolls, 6(injury)* 3 = 18 injuries a year. 162/18 = 9 games played per average injury---but he will miss 4 on average injury, so 9/13 = 69.2% games played--or 112 games played on average.
He won't get injured 18 times because he is missing 4 of every 13 games--so he really takes 12 or 13 injuries in a season.
680PA is what a lot of people assume.
In that case 680/216 = 3.14 so 6 * 3.14 = 18.84, 162/18.84 = 8.6, and 8.6/12.6 = 68.25% games played or 110 games played.
With 648 PA assumed this is my chart, not counting the green injury guys. This is in games worth of innings played in a way. Usually a 4 injury guy gets in 130 or so games--but some of them will be half games the day he got hurt.
1 = 150 games played on average
2 = 141
3 = 132.5
4 = 125
5 = 118
6 = 112
648 seems to work well for me as I often have my high injury guys remove for defense with a lead, which does knock their PA down just enough.
