Please share your TT tips

I've started TT DD on Friday and at the moment it is hit and miss. She is giving me heaps of signs that she is ready like taking her nappy off, being uncomfortable dirty/wet, waking up wet from her day sleep, has bladder control (can stop a wee), can go 1 1/2 to 2 hours without weeing. DD will wee on the potty when I catch her in time but isn't asking to go. I've had differing levels of success from her taking herself to potty to showing no sign of recognising she is weeing until she is weeing.
We went all day saturday and sunday without an accident but today we have had 3 accidents. Is she not quite ready or do I need to stick with? Heaps of people say wait until she is ready but how do I know? So everyone what do you think? What are your tips?
TIA,
Dan
