It depends on what you want to do. I used to play in a cardroom that ran a base T25, 30K. I think the 10k made a lot of sense there - one of those in each starting stack, along with two 5ks. It wasnt necessary in the beginning, but it helped later on, as this tournament would get 60-120 runners.
I’d agree that the vast majority of home tournaments don’t need anything beyond a T5k. If you’re running a base T25 and you own T25ks, I think in most cases you’re out of your mind. And even if your base is T100, I Can’t imagine how many tables and rebuys you’d need to justify a T25k.
