It's because I'm wondering if a max count is the best solution or a min size is a better solution.
A big account (1 million HP) might want to lend to 100 accounts. This account would have its HP into three accounts to do so. A small account could also do 40 delegations (let's say a 400 HP account) each 10 HP and tax the system too.
Ah I must have confused people with my explainer, see my reply to jarvie above, delegating to a pool is different from delegating rc to a user.
I'll add something to the post itself.
Sorry, my terminology was equally confusing. I meant delegating to pools not accounts. Like to a bunch of different communities for example.
Yeah I realize that now haha. Well I think 40 is a lot already, I don't think there will be that many dapps/account creation services. And even if there are, and the whale insists on delegating to all of them, the whale can make another account delegate hive power to it and then delegate rc to 40 more pools
