Great tip! Personally I would never delegate because I really enjoy curating content and encouraging the people I support.
That said I also hate when I realize my account has been at a 100% voting power. So voting only when it gets to 98% sounds like a great option.
Delegation also gives you less control. The only delegation I've done is for @qurator which is a great project. The returns are low compared to other bot delegations. But it is for a good cause.
