I'm equivocating now. Today's 1.15 shave went a little too close and I got some irritation in just two small spots. Lovely smooth and close shave with my two passes (WTG, XTG). I think I may have been pushing too much on the razor in certain classic areas (left mustache/chin area and left lower lip area). The 1.05 probably accommodated the error in my technique. The 1.15 did not. Such a close shave though, and I can tell the difference in efficiency. 1.05 is leaning towards being more face/skin friendly for now.
To be consistent, I would sometimes get careless with the Karve C plate and have this same irritation in the same places. This shave was with a GSB, fwiw.
Nowadays I don't put any pressure at all on the razor regardless of what razor it is. If it needs another pass, I do so. I have given myself nasty cuts with even razors reputed to be vey mild because I used pressure to overcome their lower efficiency.
