Basically yes because that amount of play is as close as you'll ever get to being right on. If you have a dial indicator, that's the best way to check but you can use a piece of wood and a pencil too. First thing is take the throat plate out and with the saw unplugged, mount a blade and grab it by the outer edges and do a push/pull in it. If it moves in and out very much, I mean less than .010 I would say that's ok. But anything more than that is not acceptable. Then roll the blade toward you and mark a tooth with a sharpee and place a straight edge along side of the blade and rotate the blade to that same marked tooth at the back. There should not be much deviation between the too. It can mean either an out of center shaft or the whole motor is out of alignment. That can be adjusted but the bent shaft can't. I can't remember what saw you have. Is it a motorized contractor saw or a job site saw. My saw is a jobsite saw and I have tuned it to be the best it an ever be. It will only go downhill from here.
