Manuel,
Carl already answered some of your questions, let me add on:

...Manual, I think that this part B is half the concentration of the
sodiummetaborate, it can be a problem to solute all the SMB for the
stock as Hutchings describes. If you mix half the amount you do not have
problems with precipitating SMB, but you should use twice as much
ofcourse..

..I paste a table below, but this one is for PMK, not for ABC+, not sure
if it will make a big difference..
Chart of Temperature - Time Corrections for PMK Pyro Developer
Pyro requires a correction of 4% of the listed times for each
degree F over or below 70F. The table below simplifies
calculations. For long times, 1/2 that time can be used to
find a value which is doubled.
