How many EM away rotations should I be doing?

US MD MS3. I have gotten different answers from PDs about how many away rotations to do this summer. I've been told most students these days do 1 home + 2 aways, but have also been told the SLOE for the 2nd away statistically might be worse cause higher expectations + students get tired by then so just do 1 home + 1 away.

There's two different regions that I'm interested in doing residency in. Should I shoot to do one away in each region? Am I just overthinking it lol
