Ground Types
So uh, just noticed this. probably really late. Ground is immune to electric... this site has ground taking .51% damage from electric attacks. Pokemon Go Hub has Ground taking .71 damage from Electric attacks. granted it doesn't seem like much but that is a big difference against raid bosses. can anyone confirm which one is actually correct?

An immunity multiplier now exists in Go (was introduced with the new gym system) where a type that is immune to another takes .71 * .71 damage (.51x).
Rock is not resistant to electric: Kabutops and omastar, due to their water typing, take a full 1.4x damage from electric attacks.
Pure rock types take NEUTRAL damage from electric, hence, sudowoodo takes 1.00x damage from electric type attacks.
Gengar, a ghost and poison hybrid, takes .36x damage from fighting type attacks, as ghost is immune to fighting (.71x ^2 = .51x) and poison resists fighting (.71) = .51x * .71x = .36x
Edit: removed the downvote!
