There are two special kinds of events you can time with PocketTimer - multi-lap events, and time trials (events in which individual entrants start at separate times, separated by a fixed amount). Recording times for these events proceeds normally, but after the results are recored, their are some special manipulations for examing and processing the results.
Recording times on multi-lap events is no different than recording regular events - PocketTimer lets you record any number of times for a single Bib#. After the times are recorded, you might see a display like this:
Now of course you notice that the "Place" column is bogus, since the "first place finisher" is actually someone finishing the first lap of a two-lap event; the first "real" finisher is listed here in place #6. No problem. Using the pop-up menu on the top line of the screen, select the alternate choice to All times, which is Last lap mode:
The place column is now correct. Note that the last column no longer displays Pace (speed), but is instead used to display the number of laps which were recorded for each finisher. Of course if you miss someone in one of the laps, they will be shown as having finished fewer laps, which may not be true.
To return to a display of all recorded times, use the pop-up menu to return to All times.
In a time trial, the first participant starts at time "zero" (the time when PocketTimer is started), and subsequent participants start at fixed intervals after that. If you assign Bib #s so that all participants have successive numbers, then you can use the time trial correction built into PocketTimer to correct all the times and sort the finishers correctly. As currently configured, PocketTimer requires that you do this when the clock is stopped, that is, when the event is finished and all participants have been recorded. At this point, select Offset from the menu, and enter the information as in this example:
First, check the Time Trial Offset box, which tells PocketTimer that the time offset you enter is not an overall offset (as described in the previous chapter), but rather the differential offset, that is, the time separating the starting time of each participant. Enter the separation time above in minutes and seconds, and finally, enter the Bib# of the first starter on the bottom. In this example, racer #100 is assumed to have started at the same time as the clock, so his or her time will be left as recorded. Racer #101 started one minute later, so one minute will be subtracted from his or her time (note that you don't have to click on Subtract; this is assumed once you check the Time Trial Offset box).
The one tricky thing that can occur is a last minute scratch. If, for example, racer #103 scratches after the numbers have been assigned, you should not start racer #104 one minute after racer #102; that would prevent PocketTimer from performing the correct calculation. Instead, just skip a time, and start racer #104 two minutes after #102, as would have been the case if #103 had not scratched.
Unlike the overall time offset, which can be "undone" if you add an incorrect offset, the time trial offset cannot be undone, so be sure you want to proceed before you tap on OK. Once you do, the results will be adjusted, as in this example:
Raw | Adjusted |
---|---|
![]() |
|
Raw results from a time trial, as recorded at the finish line. Note that the order is the order in which the finishers actually crossed the finish line. |
Results after adjusting with the time trial offset function. Note that the finishers have been re-sorted, and now they are listed in true order, that is, in order of their individual times, corrected for their different starting times. |
