No clear pattern....

[bjf]

yea, it affects it, but all that

matters is the amount of pheromones that reach the target. Isn't the total pheromone amount far more correlated

with that than the amount per sq inch?

[CptKipling]

Yes, but there are other

factors to consider such as the location (pits can be quite sheltered) of the pheromones.

I don't fully

understand why lower concentrations are sometimes better, but I can't rule it out.
