Sorry, I wasn't clear. The tomatoes split on the plant about 12 hours
after becoming fully ripe.

I believe splitting is usually considered to be connected with watering,
especially irregular watering, i.e. plants drying out a bit and then
getting a real drenching.

Can you just pick them slightly before fully ripe and eat them the next
day when they've finished ripening - or do they still split off the
plant?

I find Sungold is quite prone to splitting but haven't experienced much
on my Gardeners' Delight. (My watering is very hit-and-miss).
