Wheel Alignment Specs vs. PC Recommendations

Just had my Goodyear Integrity tires replaced after 30k miles with Michelin RadialX. The old tires were almost down to the wear bars but they also had excessive wear on the outside of both tires on the driver's side. Tires were rotated every 5k miles. I went to the dealer for a free alignment check and some of the numbers were out of spec. They completed a two-wheel alignment and now all numbers are within spec. I have read a lot of discussion on PriusChat regarding what would be considered optimal numbers for alignment. I was wondering if anyone would like to weigh in on how my after-alignment numbers from the dealer's specs differ from those optimal values?

Before:

LF Camber: -1.0 deg, Caster: 3.4 deg, Toe: 0.13 deg
RF Camber: -1.1 deg, Caster: 3.1 deg, Toe: -0.17 deg
Front Total Toe: -0.03 deg, Steer Ahead: 0.15 deg

LR Camber: -1.1 deg, Toe: 0.19 deg
RR Camber: -1.6 deg, Toe: 0.34 deg
Rear Total Toe: 0.53 deg, Thrust Angle: -0.07 deg

After:

LF Camber: -1.0 deg, Caster: 3.4 deg, Toe: -0.03 deg
RF Camber: -1.0 deg, Caster: 3.1 deg, Toe: -0.03 deg

Front Total Toe: -0.06 deg, Steer Ahead: 0.00 deg

LR Camber: -1.1 deg, Toe: 0.22 deg
RR Camber: -1.6 deg, Toe: 0.24 deg

Rear Total Toe: 0.46 deg, Thrust Angle: -0.01 deg

 

Anyone else care to answer?
