Tank+Status+Granularity

=What is the granularity of the ink tank and maintenance tank readings in Display Status portion of GARO Status Monitor?=

While the answer to this question is not definitive, it appears that Status Display readings are fairly coarse, with changes of 20% needed to show a change. In other words, the only readings that are displayed are 100%, 80%, 60%, 40%, and 20%. This makes it hard to determine how much ink is being used to do the daily cleanings from sleep mode, as the maintenance tank reading doesn't change and then suddenly jumps to the next lower value (20% lower). According to another poster, the increments are 10% on the printer LCD.
