FYI 89-92 turbo sups 100 is rev limit in third 
heal toe shifting(rev matching) IS an old art carried over from non synchroed trannies but it has PLENTY of purpose in modern trannies too!!! For example I downshift most allways when I am slowing down for a stop sign or stoplight or damn near any other thing I have to slow down for... By heal toeing I can down through the gears smooth enough that usualy my passengers dont know I am downshifting if the radio is on and cant hear the revs. It makes for a buttery smooth transition while still being under power at all times.. same goes for the twisties it allows you to drop into a lower gear and come out under power much smoother without upsetting the balance of the car... It sounds like a complicated technique but it really isnt! When I first started trying it was a chore to try to match the revs and brake and clutch and rev all at once and I thought I would never understand it.... Then the less I "thought" about it the more natural it becomes and easy... I can truthfully heal toe down through the gears as fast as I can by not heal toeing and the results are night and day as far as ride comfort and control... also after a while the clutch becomes more of a kind thing for the gears as when your matched up the stick is falling into place as your clutching anyways so it turns into more of a short stab then a fully depressed clutching...
I usually dont downshift untill I am under 2500 rps or so for normal driving(3500to4k if racing or running the twisties hard) and for normal driving there is usually right around a 500-700 rpm diffrence between each gear... for spirited stuffage I honestly dont know as the change is bigger and I "feel it" more then i count revs
