Nice one Michal! A real step up from when I last saw you. Railing looked great.
I don't know why this trend on the forum has started, but it's really annoying. Not ALL users that post videos are silently asking "are every single one of my tricks in the video clean?". I think we need to seriously ease up on the whole critiquing cleanliness issue and focus more on the construction/content of the video and what improvements the player has made. Maybe then players will get over their FEAR of posting videos.

If someone asks for advice that's different.
Calling the or similar should only be used when the player is/was unaware that their dexes are unclean. For example, if a player is doing a consecutive move and one is noticeably bad, you shouldn't say "sorry, your 16th was the" because obviously they know how to do the trick cleanly on both sides. We all work towards a cleaner style, but there will always be some tricks that aren't perfect. Calling the/thin especially doesn't make sense in short videos, because not every single trick may be representative of that player's typical style, and there's not enough footage to determine that.
Ftr, Greg Nelson has the cleanest merlins.
