While I am not sure that they are a reasonable way to get resources. I worked out that I would need about 200 yellorium queens to provide my power, 800 queens = 16 combs (2%) = 4 grains (25%) = 1 yellorium per bee tick.
800 queens lol? What exactly are you housing your bees in lol?
With normal Forestry/ExB mechanics you generally make sure your important production bees always produce a comb
every bee tick. This is easily done with the use of Alvearies and Frames.
Bees production chance is calculated using this formula:
P = (bee speed) * (production modifier) * (item probability) * 2^(number of frames)
The value of the "bee speed" depends on the speed trait:
Code:
Speed trait Bee speed
Slowest 0.3
Slower 0.6
Slow 0.8
Normal 1.0
Fast 1.2
Faster 1.4
Fastest 1.7
Production modifier depends on the housing. Apiary is 0.1 and Alveary is 1.0.
Item probability is the bees chance to produce the item in question. You can find this value on wikies or in NEI. Add it in decimal value, so 15% is 0.15.
The number of frames added in the formula is the number of "Untreated", "Impregnated" or "Proven" frames used.
If you want to make sure your bee produces the item every bee tick(27.5sec) then just add in all the values you know and then keep adding frames until the value exceeds 100%(1.0).
Example:
A Fast bee with a 2% chance in an Alveary:
P = 1.2 * 1.0 * 0.02 * 2^5 = 0.768
P = 1.2 * 1.0 * 0.02 * 2^6 = 1.536
6 frames in the Alveary will therefore ensure a 100% chance of production, and you should be able to manage with many less queens.
