I don't play much anymore.But I think if you want to have an infusion of new blood people need to cut down on using deadballers.
Newbies are prepared to lose.But when they can't even hit homers,that gets them too frustrated

C/A+-D/A+ defense is what I focus on when I’m using modern pitchers. It seems to work pretty well - have done OLs or themes in awhile though

I think one advantage of deadball era pitchers is that you can exploit your offensive bench more. Higher IP leads to running fewer pitchers which lets you have a larger bench on offence. Since you required identical offences you couldn't exploit this in your test. I thought the main advantage of deadball pitchers is that I can play something like 7-9 pitchers (3 starters, 1 LR, 2 setup, 1 closer, often a second LR, sometimes more) and 16-18 batters which gives me enough people to put the entire bench on if I want to save ABs on my core team. That's a lot nicer than the 10-13 pitchers (5 starters, 2 LR, 2 setup, 1 closer, sometimes more) that is more typical of modern pitchers where if you decide to (lose a game/play entirely bench) you only have 4-7 players to put on from the bench and have to use up PAs from 1-4 of your core guys in a game where you don't want to (with 5 bench starters your chances of losing are quite high so it isn't great to use up core appearances). Overall I think you can get away with lower PAs on your offensive starters when you run deadball pitchers, which means your guys are better in games that matter. I do agree if you don't get extra bench slots deadball and modern are nearly identical in performance.

The two era are dead even (with a non-meaningful advantage to modern pitchers) in RA/9. Even accounting for the extra HRs and XBH allowed, once you account for errors, they are giving up the same amount of runs. Deadball pitchers have a very minor difference in W%, one that I expect to even out before the end of this thing. Even now, the difference is equal to 1.3 wins over a full season, so is essentially a meaningless difference (81.6 wins and 80.3 win paces, respectively).

We still have a little season left, and I'd love to run another league to further test this, but I think it's fairly clear the base salary formula does a great job at pricing similar value across the pitching eras. I'd go so far as to say the only difference is preference, and the only reason deadball pitchers seem more popular is because the standard (non-error adjusted) stats don't tell the whole story, so they seem at a glance to be doing better.

In short, modern or deadball doesn't matter, you get similar overall value for your $/IP regardless of era once you account for errors and HR/XBH rates. (That said, I personally prefer modern to deadball because you can draft essentially any fielding grades, where with deadball pitchers to be more successful you'll need to focus exclusive on fielders with good-great fielding and then spend more on defense, forgoing run scoring opportunities.)
