Not a Czech but now that you mentioned it I want this here too!
I mean have you tried counting from either end using all your fingers i.e. thumb == 1? That dexterous shit is hard so making a single index finger two instantly makes it nice and smooth!
(Instant edit: this obviously only holds if index finger+ middle finger counts as 3, otherwise there really only seems to be an advantage in calling out 2 and my argument collapses)
