I think I've subscribed to all pools last year, except the cricket one. And it has been too much time consuming for me to be honest, so this year I've decided to participate to less pools and to dedicate less time to that. I also mainly bet on ML when I bet, because the hedge is usually bigger on secondary bet options. Sportbooks can hardly display shitty odds on their main pages if they want to attract and to keep customers, so they usually try to be competitive on this kind of bets.
IPL pool is very short and it's much harder there to pick if you don't know about the leagues, which I don't really, so I only took part once. Even betting on cricket I don't do so much, just here and there for IPL.
It's definitely time commitment if you want to do well, I agree. Anyone can put picks in but as you can see from people like me I do badly in most pools because I don't really follow.
Then again, luck factor like F1 I don't really know what I'm doing but so far so good lol
Same as La Liga. I know this league best but my performance? Terrible
