I guess we can have situations in life when a wall comes together at less than a 90 degree angle so then if one was putting up trim that butted at the outside corner of this wall there may be a need for more than two 45 degree bevels. Seems this going a couple of degrees past perfect is common in CSMS and such perhaps more so than in circular saws. I didn't hear anything that would make me buy this saw over the TS55 though...
Best,
