QUESTION...
0.5 grams is suppose to be the optimum
balance weight between pistons (plus pins plus rings)

WITHOUT TOUCHING THE NEW SET HERE
If I swap two gudgeon pins all four are within +/- 0.7 grams
The pins vary the most.
(rings vary by 0.07 grams)

Is this getting picky...  Should I leave well enough alone?

The new pins weigh 99 grams. the old ones  92 grams
Both are round, clean and true to 0.002"

Both new and old pins ..you can just perceive a slight
wobble of the pin in the bushing.
