What is the foil ratio for Magic the Gathering Eventide and/or Shadowmoor?

Question

I'm looking to possibly order multiple cases of Eventide but am first crunching numbers to figure out my estimated resale value doing singles to see if it will be worth it. I got all the values of rares calculated out and got my estimated value on that. Now I just need to know how frequently foils appear. I believe in the previous block it was 1:56 cards. So, need confirmation on rather it is still that way for Eventide and/or Shadowmoor (since it's the same block I'm guessing those 2 sets should for sure be the same) or if it changed what the ratio actually is.

Also....if there is no foil in the pack, you get 1 rare, 3 uncommon, and 11 common....correct?

Thanks!!!

Answer 1

As far as I know the ratio was changed to 1:70 with Torment and never further augmented.

So that would be about a foil every five boosters.

Answer 2

There is usually a foil in 1:3 booster packs, whether it is a rare or not..... I honestly do not know that ratio.
