NEW PROCEDUREIn order to avoid the “Spiders Web”
A new tracklog procedure has been proposed:
Tracklogs are left ON
On arrival at tasking, CLEAR tracklog.
At completion of tasking, SAVE tracklog.
At start of new Tasking, Clear tracklog
…and so on.
This separates each task clearly
The Tracklog page is now one of the Main pages

Minute Mayhem !
When you hear an All Teams Broadcast of “Minute Mayhem”
Change GPS to Decimal Lat / Long (eg: 34° 32.213')
Your goal is then to waypoint as many locations as you can until the stop signal
![Page 29: Overview of Today](https://reader035.vdocuments.site/reader035/viewer/2022062304/5681430f550346895daf6219/html5/thumbnails/29.jpg)
RULES OF ENGAGEMENT
The last 3 digits correspond to a time
E.g. 174° 43.245 would be 2:45pm and so on.
Either Latitude OR Longitude marks are acceptable
Bonus points for both (eg 35° 23.334' 175° 09.334 at 3:34pm)
GPS clock is the reference for time
Marks must be named using MM1, MM2, MM3 to be valid
Tips: Plan your strategy beforehand
Each minute in time equates to ±2m distance on the ground
