A statistically useful sample size for coal ward drops is around 1000.
I'm not sure any sample size will be statically meaningful when it comes to the NW random number generator. We know they are prone to bugs with regard to "randomness" i.e. dungeon chest bug, nightmare mount bug. So who knows if they are seeding properly or getting a proper distribution.
Personally, I have found it to be very streaky. I can fail 10 enchantment upgrades (with 90% success chance) in a row. Likewise I can pass 5 in a row that only had a 20% chance. While yes that is possible, statically the chance is very close to 0.
The bottom line is the drop rate is extremely low.
I don't even bother.
I just get the Sharendar Chest for a guaranteed reward (a Feyblessing for every two).
For Cols. I just buy a few Keys and open Boxes until I get enough Bars to buy a Ward. Sell the HAMSTER I get on the AH to recupe some of the cost if I can't use it.

I never dropped any coal since the drop rate nerf (and with 4 characters everyday).
Ye, i'm unlucky. Always been.
