Just because a guy is pitching on "60%" rest it doesn't actually mean they're only 60% effective, and will be running you an ERA in the 5s. Are they going to pitch as well as if they threw 100 pitches every 5 days? I'd guess probably not.

If you change guys around between SP and RP, you can see what fatigue levels they show. If you have someone who only threw 10-15 pitches a few days ago, sure, as a SP, he'll be listed at like 35%, but as a reliever he'd be 85-90% rested. That means you could run him out there for a bullpen session and he'd be fine, but he's not going to give you a starter's workload.

I think the big reason people seem confused is that, at a fundamental level, SP and RP "fatigue %" values can mean very different things. If a reliever is at 60%, it means he's probably not lasting more than like 3 batters before he gets tired, and I wouldn't bring someone like that in other than like a LOOGY just trying to get out of a jam. But a SP at 60% could actually probably still give you 3-4 innings if you needed it. But the current fatigue model does want to push pitchers to get their full rest in to fully be considered as 100% rested.

Hi Matt.. yeah I've tried they get clobbered in first 2 innings. Seems like they should be able to go 3 or 4 innings in those cases so that's another thing that makes no sense
