Returning to USA from UK after 90 days

[PSMITH20]

Hi, I'm from the UK. If I stay in the USA for 90 days with an ETSA, what is the time period that must elapse before I can return to the USA again?

There is no rule

So I could literally fly back to the UK for a few hours then return to the USA for another 90 days?

Sure. But there is an increased change that the officer may deny you entry due to immigrant intent.
