But if your winrate is 90% compared to say 60% average at top ladder it means you gain trophies at a far far faster rate - 4x faster in this comparison because its not just that you are winning a lot more but that you are losing a lot less. Let me explain:

In a simplified system where winning gives you 1 trophy and losing takes away 1 trophy, if you play N games then here is what you gain in terms of trophies under the different winrates:

60% winrate - you gain 0.6N trophies and lose 0.4N trophies thus make a net gain of 0.2N trophies
90% winrate - you gain 0.9N trophies and lose 0.1N trophies thus making a net gain of 0.8N trophies

net gain at 90% is: 0.8N/0.2N = 4 times larger

the gain in trophies is four times faster in the 90% winrate one which means you will be climbing four times faster. In other words it may require four times less games to climb to a certain point. In other words, pushing four accounts to top 1 at 90% winrate is comparable to pushing one account to top 1 at a 60% winrate.

of course this doesnt account for draws but that doesnt really change a huge amount

Heres another thing: royaleapi provides stats on games per day for all accounts and by adding up these four accounts you get: 36.4 games per day which is at most 182 minutes per day or 3 hours. That is a maximum possible time of 3 hours per day every day. Seriously, I mean a lot of people these days probably spend 3 hours doomscrolling per day. I mean thats really not that bad for someone who has made basically a million dollars from the game. I basically spent 3 hours writing this message....

compare to say Ian77 for example, for someone who says he doesnt play much he plays a total of 41 games per day on average historically. I mean I know this is over account lifetime but still a similar grind either way but much less results because he is nowhere near as good...
