inb4 pro/am joke
This a huge misconception. You're assuming pro skiers go out everyday and throw insane hammers, doubles and flips off rails every single hit. Do you honestly expect that to happen? How do you think they got to where they are now? Everyone needs to work on something to progress to a new trick. You might see Bobby brown doing a switch 5 all day in park and think "wow he sucks"... but there a ton of reasons why he might be doing that. Maybe hes working on a new axis for a switch dub, maybe hes trying a new grab to throw into a double he already knows. Or maybe he just wants to do the tricks that he thinks are fun because he wants a break from contest tricks.
Pros dont go to PC and Breck everyday and say "yes! The gapers are coming, i have to impress them with my hardest tricks all day and on every feature!"
That'd be similar to assuming a guitarist picks up his guitar and writes an album quality song every single day. Or an artist picking up a brush and painting a masterpiece everyday. There are stages to progression.
The tricks you see in video parts or an edit, for example, take a really long time to perfect. Skiers dont go to the resort with a filmer and trick idea then immediately stomp it and call it a day. It can take hours. They work for those shots and often have to land the trick several times before they're happy with it.
Side note: have you ever seen a skateboard demo before? It defies your expectation of the skaters because they certainly dont land their tricks first try every time.
