Thanks in advance.
Hello Rosenblumr and welcome to the Forum. I don't think that there are any standard solving times, it's just your personal best. The first one I did didn't have a rating, although the instructions did say that it was "one of the easier ones, since this was the first one to be published" - and it wasn't called sudoku! I thought it was a simple little game that would take me a matter of moments when in actual fact it totally absorbed me for over an hour (maybe more, I wasn't timing myself).
It depends a great deal on the difficulty of the puzzle also, although as you can see Hud is right up there when it comes to fast - to me 35 minutes for a V.Hard is astonishingly fast. I think it depends on personal preference. If timing is important to you then concentrate on getting faster and that would take practice and learning advanced techniques/doing without pencil marks. Myself, I enjoy the solving process of the puzzle, especially if it's a well constructed, symmetrical and challenging puzzle, so timing isn't as important to me as finishing the puzzle - in the past I've completed a Pappocom Fiendish in 3 days!
I know when to progress to a higher level because the level of puzzle I'm solving is too easy for me, i.e. it starts to feel like I'm just filling in the numbers and not thinking about how to solve it which ceases to be challenging, but that's personal preference. I also like to change puzzle setter (i.e. who creates the puzzle) from time to time to keep me challenged and sometimes this entails going down a level and thus affects my speed.
Timing of puzzles comes into it's own when you are competing in competitions. Other than that I think that how you play the game in general is all personal preference.
