Rogue60 is on the money here.
He is correct when he says about the chain being more efficient if the chain has equal length cutters.
Talking about saw set is important and when your cutting large amounts such as he is in commercial settings, then yes, you get more with a correctly sharpened chain with equal length cutters.
having sharpened circular saw blades on firewood benches, I both respect and appreciate what he is saying, and he is correct in saying it.
Now in saying that, if I rock a chain side, or hit a few cutters with some wire, and damage a few, I am not going to take down the rest of the cutters on that chain to all equal length, I will put up with a few shorter ones, or a side of shorter ones, and gradually work to file them back over time to get them more equal, but I dont need, or choose not to have the efficiency that Rogue60 does, and I wish to make the chain life as long as possible by only shortening the cutters with the damage, not the entire chain.
So correctly setting the depth gauge / raker height to each tooth will enable me to continue to cut straight cuts and put firewood in the trailer, will it be slower over a day, yes, will it be less efficient, yes, is it ideal, no, but can I do it and cut straight. Yes.
If I had a stand of trees along a fence line to deal with, I would tackle the chain as per Rogue60's advice, and enjoy what it has to offer.

So knowing that you can make an informed decision and decide what to do for your own situation.
