Does an extended opening shown on TV count as a tv size?
Good question huh. Point for you.
On serious note - yes, long size + marathon are different from tv-size but to be fairly honest - tv-size will carry you only till certain point and without ability to properly and consistently play long amp/marathons you will just get stuck there.
From other side - long maps / marathons can carry you way higher than only tv-size, at least it looks like that for me since my osu song collection contain in 90% only long maps and marathons and it's still shittons of maps starting from 2* and ending on 8*.
Double time dedicated players can be carried a lot by tv-size since short length being fairly easy to farm up and not draining stamina like long maps.
