By mistake I sharpened my .325 chain with the 13/64. The saw cut great. I know that .325 calls for 3/16. Any thoughts or comments. I think that I probably should keep using the 13/64 on that chain. Also, from what I read, Stihl 3/8 chain calls for 7/32 whereas other 3/8 chains call for the 13/64. Do I have that right?
