How accurately do you record your freefall time?

[Orange1 0]

As the title says - I've noticed some people will log the exact freefall time per the calcs, while others round off (usually up) to the closest 5 seconds... I've put "other" as an option in case there is some other option that I haven't thought about yet, if you do answer other please explain!

i VOTED OTHER...
i generally use :
1 MINUTE FOR ALTITUDE JUMP
0 for hop n' pop
2 min for wingsuit

Sometimes round up to 30 seconds...

I use a Pro-track, which records my freefall time for me.

Before I got that, I would just put down the estimated time from doing the maths, but didn't round it.

I've always had a pro-track since coming of student status - takes the guess work out.

you answered 'exactly' for using a pro-track then?

Don't log freefall time, one day I may have to go back and guess if I need it for ratings

I answered other... because before I got my protrack I would estimate based on what kind of jump I was doing... 60 sec for full alti (although I would use the scale and estimate for lower altitude jumps.)

Now my times are logged according to the protrack.

Other. Don't calculate it. I am as bad/good as I am. Some statistical numbers won't change it.

I'm having enough problems remembering to log my jumps, heh.

I use a Pro track. Much easier and more exact.

I have a Protrack now, accordingly I record my time exactly. Before that I used estimates to the nearest 5secs.

My precision is 1 second; my accuracy is closer to 5 seconds because I don't use a Neptune or equivalent.

Mostly I worked off the chart, assuming a faster fall rate and WAGing it. When I had a neptune demo, I used exact, save the jumps where it was clearly wrong (average speed of 165 for a belly, 0 mph at 12k interval). It also seems that FF on the neptune continues until your parachute has fully deaccelerated you, which may be different from the chart going to deploy time.

For whatever accuracy it represents, I passed an hour last weekend.

I use a Protrack...and I think it sneaks you an extra couple of seconds while that canopy is deploying. It always says my deployment altitudes are lower than when I tossed my hackey.

In the US, most S&TA will not approve jump and freefall time awards without a logbook entry or other written proof. Mine has told me the protrac is not suitable proof of jumps or time since anyone can take the protrac and jump with it.

I log my rounded freefall time from the protrac's individual jump data screen and then periodically insert the exact time (HH:MM:SS) to verify the totals and reference tie to protrac time.

I keep accurate records to the second.

Anyone can fill in a log book too! At least the protract has to get into the air to log its dives.

My freefall time is logged on my Neptune. I transfered my then-current total onto the device (along with my jump numbers) when I started jumping it.

A one second error a jump for 4500 jumps is 1 hour 15 min...

How accurately do you think you should log?

hehe, you know the difference between precision and accuracy!
I would say that I log about the same as you. Precise to 1 second; accurate to 5 seconds.

can't afford to buy pro track...

10 sec for the 1st thousand
5 sec for the passing 1 thousand feet... i don't know if this is accurate.. read this somewhere here in the internet...

This is pretty much what I do, too. I use 3 to 5 secs for hop-n-pop.
