Your pro track doesn't know when you pull the pilot chute. It registers when you slow down past a certain point.

When your canopy is fully open.

And how do you suppose the PT knows when your canopy is fully open? Does it look up and check? I don't think so. There has to a magic number or formula there somewhere. Anyone know what it is?

Nope, and the manual doesn't say. It does say that it's accurate to +- 100 feet.

Amir, have you emailed L-n-B yet? They are VERY awesome when it comes to answering your questions.
That is a good question. Perhaps you could put your findings here when you know.

I remember this coming up before. You might want to do a search.

I've been looking around and this little snippit from L & Bs website seems to confirm that they're using a formula rather than a hard number to determine opening.

From http://www.l-and-b.dk/asp/faq.asp?mode=Protrack
The deployment altitude recorded by the PRO-TRACK is the altitude when the canopy has been deployed and the speed starts to slow down. The PRO-TRACK cannot sense when you throw out the pilot chute. You are right; the altitude at which you throw out the pilot chute and the altitude the canopy is deployed can be very different.

Of course for the definitive answer you need to email the good folks at L&B.
