So this heal toe you speak of

i actually did the exact opposite than Ciro when i was learning to rev match. after i was reasonably decent at estimating the rev-increase for each downshift based on various road speeds (by looking at the tach), i'd put an index card taped over the tach. this made me force myself to learn based on sound, vibration and pedal feel. it was rough at first but i got acclimated in a week or two of constant driving. nowadays i can rev match pretty well without concentrating on the gauges
