Meteorite Spawning Question (also a question about Meteor Armor)

[Flubman]

I know that defeating EoW/BoC gives you a 50% chance of a meteorite spawning. However, do the chances for a meteorite spawning stack if you defeat multiple EoW/BoC in one day? Like, if you beat two in a day, would that increase the chances of a meteorite spawning to 75%?

Edit: Also, is Meteor Armor even worth getting anymore after JE?

Pretty sure the chances are affected by smashing shadow orbs/crimson hearts

Not since 1.4.
