Estimated fragment/vaal gem chance?

So far I'm leaning towards 50% which doesn't seem very impressive. Still burning corrupted maps.
So far 3 frags 6 maps.

70:30. F:G

It seems the chance to drop a fragment or vaal skill gem is really low. From running 5 maps so far with 26 bosses (twinned museum, 2x twinned dry forest, 2x twinned bazaar) I've gotten 7 fragments and 1 Vaal skill. This is about 30% chance to drop either fragment or vaal gem.

25 bosses killed;

frag: 52%
nothing: 40%
gem: 8%

A twinned museum / bazaar will get you 3 frags, so thats nice

I guess the quantity of the map plays a role..

so far i ran 17 white corrupted maps, level between 67-73, 6 fragments 0 gems

so 35% on whites for me

It was confirmed by Chris that quantity does not.

Yeah I did some stupid 8-mod maps and it still boils down to 50% to get something.
