You keep asking questions, trying to deflect from what is quite a simple point, that a suggestion was made (not by you) that stopping to wipe finger prints from the rifle would mean Oswald needed to fly down the stairs rather than take a brisk walk. I am asking for a fact to support that suggestion. If you can't provide one I'm not sure why you are commenting or what you are trying to achieve.
You should be asking why flying down the stairs automatically makes you winded? Don't get hung up on semantics. My "guessitmate" that Oswald was moving quickly down the stairs was because approx. 90 seconds after the shots rang out, Oswald was encountered in the second-floor lunchroom by Dallas police officer Marrion L, who did not notice that Oswald was winded. Obviously I can't prove it was impossible for Oswald to have done that, only that IMO it was improbable. The onus is on you to rebuke my guessimate by demonstrating it was possible. Otherwise, I'm not married to it and it doesn't make Oswald a LN by default.
If you can take 3 shots, wipe down the rifle of all your prints, ditch it as shown in the Alyea film and get to the 2nd floor in 90 seconds I will concede that it was possible. But I still wouldn't believe that's how it went down because that's just 1 piece of evidence, of many, that casts doubt on Oswald being the shooter. So instead of tying myself into knots trying to make the LN narrative fit, I go with Occam's Razor and the patsy hypothesis fits like a glove. But that's JMHO, believe what you like.
