yes, usually a libero takes a point only when he did it by chance (actually, I've never seen before a libero scoring on porpuse!), and because this time it wasn't, Legavolley system registeres it as opponent errors! about that I loved the article on GazzettaXD
what is weird, points scored by liberos are taken as opponent mistake, because system doesn't expect from libero scoring points... that's why Henno on Cuneo's website got this points, but in report with statistics no.
he studied this situation (he knows where Paparoni goes in similar actions) and did it on porpuse=)
Vermiglio is quite disappointed ?
