Here is an updated altitude vs time plot for the 60 sats of the Starlink V1.0 Batch 1 (Launch 1) set. 20 sats (blue) at 550 km. 20 sats (magenta) climbing at 400 km, 20 sats *cyan) still at 350 km. 2 of 4 deployment rods (green) now reentered.

What's happening here: at the 350 km altitude the orbital plane precesses at a different speed from the 550 km orbits. So they are delaying orbit raising  until the sats get to the desired planes, thus filling 3  orbital planes with one launch
