This issue may occur when you select "Log flight time in Decimal Hours"
PILOTLOG always stores all flight times as minutes in the database, even when you choose "I log flights in Decimal Hours" on the Settings - General page! By default, flight times are saved with the highest accuracy.
However, when "I log flights in Decimal Hours" is selected, flight times are rounded to the nearest decimal for on-screen display and for paper printing (logbook and reports).
Here is a sample :
You log a flight from 08:00 to 08:14, and another flight from 10:00 to 10:38. These flights are stored in the database as 14 minutes and 38 minutes, regardless of your settings. If you print the logbook in decimal hours, the first flight is displayed as 0.2 hours and the second flight is shown as 0.6 hours. However, when it comes to totals at the bottom of the page, the software calculates 52 minutes, which is displayed as 0.9 hours...
One can argue whether the logbook should display 0.8 instead of 0.9 hours...
Our policy is that the logbook should represent as much as possible your actual experience, and not an inaccurate sum of rounded values, which can lead to a significant error over time. Also, should you ever decide to switch-over from decimals H.h to hours-minutes H:MM your flight experience remains unchanged.
Nevertheless, you can avoid the issue by selecting "Rounded (Decimals - 6 minutes)" on the Settings - General page. In this case, PILOTLOG will still save flight times as minutes in the database, but rounded to the nearest decimal.
We retake the above sample :
You log a flight from 08:00 to 08:14, and another flight from 10:00 to 10:38. With "Rounded" selected on the Settings page, flight times are no longer saved in the database as 14 minutes and 38 minutes, but as rounded values of 12 minutes and 36 minutes. Now, if you print logbook in decimal hours, the first flight is displayed as 0.2 hours and the second flight is shown as 0.6 hours. Totals at the bottom of the page are calculated as 48 minutes, which is displayed as 0.8 hours...
The accuracy selection on the Settings page is for new entries only. Changing the selection from "Precise" to "Rounded" (or the other way) does not apply backwards.
