Subtract the injury rating from 23.
Multiply the result by half the injury rating.
That's it.
23 - inj. Then .... "The result" times inj/2.
23-1 = 22. ..... 22 times 1/2 = 11. .... 1 injury = 11 games missed, including "the rest of game" (so there are fewer than 11 STARTS missed).
23-5 = 18. .... 18 times 5/2 = 45. ... 5 injury = 45 games missed. (Includes "rest of game," so there are fewer than 45 STARTS missed.)
This is just a rough estimate for a middle-of-the-lineup guy on an average scoring team. Increase the number of games missed for lead-off hitters and high scoring teams; decrease the number for ninth hitters and low-scoring teams. Why?: The real formula is based on how many PAs a full-time player "would have" at a certain line-up position on a certain (high or low scoring) team, if never injured. The more exact short-hand formula is on some other post .
Note that this does not account for standard deviation, which is the REAL risk in higher injury ratings. It just gives the average, over a huge number of seasons.
