-Totally random number tbh, for some formats a 50BI downswing is rare-ish for others it's just another Sunday.
-Less % of field paid/more % of prize pool at top places=more variance=bigger downswings. So generally more people playing results in bigger downswings. 50BI downswings in 180 mans as an example are pretty much completely standard.
-Honestly my advice would be is make sure you're playing as optimal as possible and don't worry about the rest.
-First of all 35BI downswing in 18mans is totally standard (don't think there is a format left where it would be considered rare). Take a break if you need to or drop your volume for a while, but if you can't deal with **** like that get out now. It won't be your worst downswing, expect to hit the magic 50BI downswing one day and if you're really lucky expect to hit a tripple digits one magical day
. Other general tips are have solid BRM strategy ready for when things get out of hand, don't watch all ins, force yourself to be in a good mood before you start a session,...
