you have to think of it is 2 different jobs -- in what they do on field as well as preperation.

i.e. when a RL RP goes from pen to starting, he doesn't just need a few days off. he needs to work his pitch count up -- regardless of his innate stamina. we don't have to worry about that in ootp, of course. if rested, set position and go.

also, RP get a bonus to stuff in ootp. this simulates the fact they are throwing harder and fewer pitches per outing is likely from the extra exertion.

while they throw the same types of pitches, they do it in different ways and with different constraints due to context. one has to last, one is expecting going all out for no more than ~40pitches. (injury starts sky-rocketing if you go over 40 pitches in 1 inning, 40 accross 2ip more likely, but still not expecting to last long and exerting more due to that fact)

it's like comparing a 2B to SS or LF to RF. think of it like that, and it's not so odd. 2 very distinct positions that that have similarities.

side note: they supposedly adjusted long releif or relief # of pitches per stamina a bit. i have no experience beyond what i read in the patch note on it though.
