I found Nilfheim's blank numbers.
20 Chi (Delta), 4067 Phi (Zeta/Epsilon), and 811,348 Upsilon (Minor Psyker).
Basically, the psyker scale goes
Alpha + / NA
Alpha / Omega - Immune? Incredible Calming.
Beta / Omega Near Immune, Massive Calming
Gamma / Psi Incredible Resistance, Major Calming
Delta / Chi Massive Resistance, Significant Calming
Epsilon /
Zeta / Phi Major Resistance, and a slight calming effect.
Eta /
Theta / Upsilon This is where High end Minor Psykers are.
Iota / Upsilons have Significant resistance
Kappa /
Lambda / Tau This is where low end Minor Psykers are.
Mu / Tau have a slight resistance
Nu /
Xi / Sigma This is where psychically sensitive people are.
Omicron / Sigma have a very slight resistance
Pi /
Rho / This is normal humanity.

1. Given the centuries of Evolution the Avernites have gone through, have we noticed a massive increase in population of the Nu/Xi/Omicron numbers? Are these minor psykers, or does the Telepathica not bother with them?
2. If you put a psyker and a blank of equal powers in a fight, does the blank mostly win?
3. What are the Nilfheimers training right now? Is it every Phi/Chi with some select Upsilons?
