The system draws from the surplus first instead of the daily allocation, making it look like I'm in the red when I actually have hundreds of MB left. The same applies for the accumulated surplus it assumes that all data transferred so far was a part of the preceding day(s) allotment, and doesn't take into account that some usage was from today or that there was an allocation made specifically for said usage. In other words, this figure is only really accurate between midnight and the first byte of network activity of a given day, and approaches a greater degree of accuracy the more days go by. The "remainder of the month" calculation assumes that the current day has not yet begun and merely divides the total MB available for the month by the number of days left, where it should take into account the % of the current day already over and how much data is being used daily. ![]() Today, while still more than 400MB below my daily allotment, the Accumulated Surplus reads -45.3MB, and the "remainder of month" calculation is in the red, even though the average daily usage is just over half of the daily allowance. As an example, I started a usage cycle yesterday, and during the day used ~300MB less than my daily allotment. ![]() ![]() I've been testing SurplusMeter v2.0.3 since January, and I found that these figures are unreliable, based on the way they are calculated. A promising app, and a useful program concept, bit I can't help but notice the Accumulated Surplus calculation is occasionally way off, as is the remainder of month calculation.
