Front white: 3.24/3.46, blue: 3.84/3.73
Rear white: 3.09/3.06, black: 2.80/2.80
Only one pair of the lot are matched. How critical is it to have matched pairs left and right?
You might want to do a guage study on your test jig. Fixturing of the spring and differences in the measurement process could also lead to the results you are seeing.
