I certainly have had experiences with razors that I "nail it" upon first use:"Nailing it [optimal shave angle] on the first shave is the exception": Hmm....this is precisely my experience with the Winning, Dart, and R41. The shave angle for these was absolutely intuitive for me right on the very first shave: Excellent performance and zero learning curve or irritation.
This experience has set my expectations for a razor's potential performance, as I like the shaves I'm getting now with the technique that feels most natural to me. Maybe I'm missing out on razors that need a shallower angle, but my shaves are so good that I'm fine with that right now. Life's too short for sub-par shaves

I do believe that one's ability to get a great shave from a brand-new razor is somewhat tied to how much experience you have shaving with DE's, and also, perhaps, how often you *change* razors... What I mean by that is: I very often select a different razor (from a rotation of 6) each time I shave. Not always, but frequently. I hardly ever use the same razor for weeks straight, unless it is a new razor and I'm trying to evaluate/figure out.
Because I change (rotate?) razors so often, I think I've learned/conditioned myself to really stay attuned to how the razor *wants* to work, and adjust to that based upon initial feedback from the first few strokes. Pressure and angle mostly are the variables to quickly dial-in. I never try to impose a specific shaving angle onto a razor, for example. It's one reason why I question when other Members talk about "shaving steep" with a Blackbird, for example. The beveled head-design of that razor, in particular, IS the guide for proper angle, as the Maker intended it. Why fight that?
