"The blade is better supported with closer guide roller settings and won't wander as much, if you care about squareness, then ?use the OEM setting. ?If squareness of cut is not that important to you, then more clearance will make the bearings last longer."
?
And in the context of us hobby users, "longer bearing life" means something like lasting until the year 2150.? A lesser clearance will still let the bearings outlive you.?

Regarding set-up/alignment, I'm not saying it was the procedure mentioned above, but I followed one I got off some machining group and it took my saw from cutting less than 0.005 in/in squareness to about 0.040 in/in.? It was complicated, very involved, and counter-productive.? The process is inherently somewhat simple as there aren't a lot of places where you can make adjustments.? The bigger problem I found was that the fit of the parts wasn't very good. The most valuable thing I did was to square up and shim the moving surfaces on the guides to make sure that adjustment and tightening screws didn't move things around.? Then I used the procedure out of the saw manual.? It's back to cutting square, better than before.
