Assuming 7 here means Z, the Z axis fluctuates in the + range. All
three axis seem to hold to 4k most of the time (+ or - for X and Y,
only + for Z), with not infrequent peaks of 8k (+ or - for X and Y,
only + for Z), and seldom peaks at around 12k. Z seems to peak to 12k
more often, I only rarely manage to see X or Y peaking so high.
