Piston and conrod weights

[Flatplane8]

Any of you home AJP rebuilders bothering about the weights of the pistons, conrods etc? The factory manual said to select 'pistons that are within 1 gram of each other'. My heaviest piston is 2.82g more than the lightest. I've tried to weigh the small ends using this lash-up and that gives a combined piston-small end weight spread of 3.7g. Curious, but also mindful that this combo has done 170k miles like this.....
