AFR misleading? Plugs tell a better story?

The comp numbers look ok to me not great but ok. Warm test might show different. Any weird carbon tracking in the cap? If I was tuning this I would get wot afr squared away where I wanted it prob around 12.5:1, get the cruise afr pretty lean 14.5:1 and just deal with whatever that cam delivers afr wise on idle. Like mderoy340 said that cam will have some reversion at idle. Set the mixture screws for the best idle vacuum and live with it. All of this after finding the source of the misfire.
