The thing to remember about powders is that each kernel is probably different from the next kernel, not to mention that the fact that from day to day, each kernel is different from what it was yesterday, due to such factors as greater age, differing humidity and other meteorological conditions, the phase of the moon, and whether or not it got a good night's sleep. Given this, a load that was acceptable yesterday should probably be reduced 10% today and worked up as (unreliable) signs indicate.
