1.4 injury ???

checking some other sets of players other than ATG, I noticed some players have injuries with decimal points

back to 80s set, for example

Eric Davis is 1.4 injury rating

a look at general 365 rules states only player sets from 2000+ or like that uses "super advanced injury chart"

so, seemingly, back to 80s uses standard version with 0-6 only, no mention of decimals, and no way of knowing how often this guy could get injured

any info about this decimal injury rating, and ideally a chart/link as to how to read and evaluate them ?

thanks for playing

Another aspect of a mystery card set. That rating is the avg injury chance of his 5 years
