I imagine there is a dose response relationship
Given laryngophed was outlining a low emetogenic strategy, I thought I should point out using “lots of ketamine intraop” may be counterproductive

I guess it depends on the definition of "lots." For procedures like spines, hearts, big ex-laps, etc, I see a large opioid-sparring effect with 0.5-1mg/kg ketamine at it near induction, without increase in nausea or sedation in PACU. I imagine 2-3mg/kg might cause some nausea, as the room spins, melts, and turns into a puddle of elephants.

It's mostly emetogenic during it's most active phase so for 20-30min.

I see. I frequently use adjunct dose (<2 mg/kg cumulative ) ketamine for MACs and spines and I've never had PONV issues, but of course the concomitant propofol infusion might just mask any effect.
