it's not like you can come over to very efficient encoding scheme because you need to encode everything pretty much with some reasonable probability you're gonna have to send it across whereas here on the right what happens is this first outcome over here scroll ugly so if you encode that first outcome with a very small number of bits then most of the time you have to send almost nothing and then yet sometimes you have to send more bits to get the other things across but most of the time is very cheap and so that that's effectively what's going
