The evaluation of this group of plots is:
(a) the solution strength is decreasing.
(b) replenishment rate must be increased to bring the gamma back up to the target line.

f. Figure 30 shows the same thing, only in reverse. Apparently the operator overcorrected the
replenishment (from the low trend) and now there is a high trend.
Evaluation:
(a) Solution strength is increasing.
(b) Solution replenishment must be decreased to bring gamma back down towards the target line.
