[RASMB] timing of auc runs

[Judith Kornblatt]

How consistent should the length of time for a run be? I've been doing 
the same basic run multiple times - same speed, same number of scans - 
and the total time for the run, as displayed on the panel of the AUC, 
varies considerably. For example, 200 scans, 32000 rpm, the times varied 
from 13:15 to 14:51. More recently, 200 scans at 37000, times varied 
from about 13 hours to 14 hours. Is this variation normal?
