Balancing Pitching Stats

[Heckah]

I don't know if this would go here or in theory/discussion. But I'm looking for some thoughts on when to call off the dogs or keep the foot on the pedal when it comes to pitching.

H2H weekly league with six pitching stats. W, SV, K, ERA, WHIP, QS

Currently...

Up in W 4-2
Punted saves
Up in Ks 42-29
Up in ERA 2.68-4.03
Up in WHIP 0.98-1.55
QS tied at 2-2

I have Musgrove today and Cueto tomorrow and I'm out of moves for the week
He has Urena and Carlos Martinez today and Giolito tomorrow and can add 2 more pitchers for tomorrow if he wants.

I'm fairly comfortable this week keeping the pitching going to pick up more Ks, Ws and QSs, to outlast the potentially 5 starts he can throw at me because he probably has the larger risk to his ERA and WHIP than I do, but is there a point where you are willing to bench your starters to preserve ERA and WHIP?

Sure, there's a time, but there's no formula, at least not for me - it's a feel thing. Depends on how the other categories (including hitting) are fleshing out and what scenario gives me the best chance to win. It's not always possible, since it is schedule and rules dependent, but midweek I look to stash a possible streamer for Sunday in case I need him.
