Certain arguments are based on tewari but may be questionable as applied in practice. Typically they re-order a sequence in such a way that one player is thought to gain on balance out of two identifiable mistakes or poor exchanges, one of which counts against Black and one against White. If each of those could really be quantified as a loss of a certain number of points, then they could be set against each other for a conclusion that the sequence as a whole changed the score by the difference involved (that is, assuming all the other plays involved no loss at all). The tewari technique of permuting plays would be justified, because the loss made in the transition from the initial to the final position really doesn't depend on the path taken. Suspicions are aroused, in general, by this kind of argument. It probably applies well enough in many endgame positions. It is much harder to be sure of the reasoning when looking at a sub-board, or in complex middle game positions. Pros do use tewari - I was shown an example by Sonoda Yuichi as applied to a purported 'joseki'. Generally speaking, the more reputable applications of tewari reasoning are one-sided: after re-ordering the sequence, one of the players is seen to have done something loss-making or unnatural, while the other player's choices seem normal and good.
