Interesting Turbomiles rule -- it could cost me a trip count.

I'm scheduled this Saturday to fly MKE-DTW-PHX, then about 3 hours later PHX-MSP-MIA. I have an overnight in MIA then on Sunday fly MIA-MSP-PHX. I then stay overnight in PHX (I wanted a few hours to do some things in PHX) and on Monday I fly PHX-DTW-MKE.

I guess given the 4-hour rule that they may call this all one trip, but maybe it'll be two trips because I'm flying back on two separate days. Who knows?-
