Target CPA and High CPC
try not to use SKAG - use STAG or IBAG - this also includes you put a whole bunch of KW but all are disqualified except 1.... then it becomes a SKAG again.
To lower - mix some high performing KWs from Google Search Console into the group (if possible) - make sure they follow the same theme(STAG)/Intention(IBAG). - these will usually super perform better, you are going to burn money if you are going to push unrelated KW in an attempt to break new grounds
Lowering CPA cost or budget or any other cost - do it at a 10% ~ 20% interval - usually machine is programmed to have a over spend of 25% so of you lower too far, it will jam for awhile so it can "re-allign", larger the drop the longer the "re-allignment"
There is a 1~10 Quality score involved - so your $25 cost paid could be a max $250 bid.... don't be afraid
