It roughly goes like this:
Group 3 - Jets with a few slow exceptions
Group 2 - Fast turboprops, slow jets
Group 1 - Turboprops.
Group 0 - Pistons and very slow turboprops (e.g. SH36)
If routes track 45+ degrees apart after departure, 1 minute separation.
Otherwise separation is 2 minutes or for some interacting routes 3 minutes.
Then if the slower type is first, add the difference between the groups on the speed table e.g. piston followed by a jet = 2 + 3 = 5 minutes, turboprop followed by a jet 2 + 2 = 4 minutes.
However if the following aircraft is more than 2 groups slower than the preceding one then the overall separation is 1 minute e.g. Jet followed by Turboprop = 1 minute
The details differ from unit to unit based on local experience and of course vortex overrides these.
