Hmm. My daughter turned 2 a few months ago. We've been doing EC most of the time since she was 3 months old. She's gone through phases when she is near 100% with the potty, but not now, for whatever reason (I'm pregnant, therefore more tired and distracted than usual, she's been sick, etc.) She does always go to the potty for poos, though, which is a very good thing.
When she was younger, she used to pee 20+ times in 24 hours. Now, I think it's more like 8 (on average), and there are days we change her diaper 6 or more times... and I don't EC at night any more, so that's a maximum of 3 diapers from bedtime to waking up in the morning.
ETA: I counted diapers again yesterday (my mother was taking care of her most of the day, so she only used the potty for poo) and it's more like 12 times in 24 hours. I don't understand why she's still peeing so much at night, but there it is.)
How old is your toddler? Pee frequency does decrease, eventually, but then there are bigger, stinkier pees IME.
