0.8 flight time, 10x around pattern. 2 Pipers in the pattern when I started. One did a full stop about 3 patterns in, the other at about 6. Another guy called 3 mile final between me (on base) and the Piper in front. I told him where I was and he did a 360 for spacing. Hot, humid, overcast this morning. Engine is too rich right now - only seeing low 1200's on the EGT on takeoff. 56 landings on this 2nd side of the 1st set of tires now - we'll see how long they last. Been maximizing the number of landings while minimizing the amount of taxi distance. Today only taxied down to the new turn-around area, so did an intersection takeoff instead of taxiing all the way down.
