I mean, the side the chain is on - as opposed to the side the crankcase cover is on. I thought I was keeping them the same length because i was counting strokes but the calipers told me I wasn't. My strokes were not equal on the two sides.
I don't use the caliper in the field or every touchup. Only before I work on the rakers.
That's pretty common, since most people are stronger with one hand than the other. Some folks get into the habit of taking an extra stroke when filing on their weaker side (the one where your cutters are coming out longer) to compensate.
I just eyeball my cutter lengths, and don't get all that worried of they are a bit mismatched. If you use a progressive tool for setting your depth gauges, keeping all your cutters the same length is far less critical.
If the only tool you have is a hammer, you tend to see every problem as a nail.   - Abraham Maslow

Using a 372. I don't really care if the teeth are shorter or longer than others. I just make sure the bar is dressed properly (straight, 90 degr) and that the rakers are set right. I've cut with chains with teeth filed down to the line on some, while others are longer (mainly due to hitting nails or fence parts left in trees, and having to completely re-create work corner of the tooth). Just have a consistent raker depth, a square bar, and the saw will cut straight.

I usually machine sharpen after every 5-6 hand filings, unless the tooth lengths are very different across the chain, and require machine adjustments. I put the chains back on the machine grinder just to dress up angles.

I agree that the cutters don't have to be the same length as long as the rakers are set properly.   Nevertheless, I try (slightly obsessively) to keep all the cutters the same length (about about 1/32 in. tolerance) except where some have been damaged. That way, I can use a "consistent" raker setting - which is easier to maintain in the field than a progressive depth to each cutter/raker.
I had one chain that suffered barbed-wire damage to three successive cutters on one side. I cut those three back to a consistent size with each other. I did the same for the three cutters on the opposite side, then set all six rakers with a progressive depth gauge. cuts better than new.
Why do I worry about consistent cutter length while admitting that some can be shorter? Because I do use a "consistent" raker depth every where that I can and because I want to count strokes when doing fast field sharpening. I (generally) correct damage and set rakers progressively only in the shop. I like to leave in the morning with a chain that is as perfect as I can get it.
Using the Granberg, I hope to reduce my cutter length tolerance to about 1/64 in or less.
Anal? Yeah, maybe - but it makes me feel better when I'm milling super-hardwoods.
