Color Bias?

Can someone explain how the color bias in a starting pool is supposed to work? I chose red, and was expecting most (> 60%) of the 150 common/uncommon/rare cards that went into my starting pool would be red. Instead, I'm pretty sure it wasn't even 1/3 of the pool.

I think the percentage is based on your quest preference color bias setting (1 lowest, 10 highest). While it's based on the number, that doesn't mean is 60% however.

It's certainly biasing the new quest, I just started one, and I have 43 Red cards, and about 12-15 in any other color. So that's about 40% of the biased color.

Glancing quickly at the code the way it seems to work is take the normal distribution and adjusts it by doing the following:

Normal Distribution = 1 Multicolor, 3 Colorless, 4 of Each Color. Randomizes this list and loops through this to generate roughly even distribution of each rarity.

Biased Distribtuion = 1 Multicolor, 2 Colorless, 3 of Each Color, X of Biased Color, where X is either the Biased value (or related to the Biased value). Which comes out of the boc as 6.
