calculating fall rates question

[usmcdannyboy 0]

ok i was looking at the fall rates in the back of my log book and accoriding to their calculations i should be falling around 109mph but i know for sure that i fall like a ton of lead. and i dont wear a stop watch for fear of confusing it with my alti. so whats the deal ? do i fall at 120 like i have been told or is it 109 like the book says...someone looking at my log book would question my integrity if i were all of a sudden to go from a 60 sec jump at 14,000 to a 72 sec jump from the same altitude

Well, lessee . . .

Do you do freefall belly-to-earth with other people?

Do they consider you "floaty" or "fast"?

If you're "floaty" my -guess- is that you're probably not falling any slower than about 110 mph true.

If you're "fast" my -guess- is that you're probably not falling any faster than about 135 mph true.

Those are "about" the limits of what most people can normally do belly-to-earth for a "normal" freefall formation without some sort of freekish thing going on. (For instance -- 6'10", and 100 pounds or 5'2" and 240 pounds -- ya know -- freekish).

In -my- experience, -most- casual RW groups at Perris fall between 115-120 mph true. -Some- hot 4-ways (teams) will fall a bit faster, maybe 120-125 mph true. "Normal" fall rates do change from dropzone to dropzone and even load organizer to load organizer at a single dropzone.

The answer is quite simple, my son--

Get a Pro-Track-- And all confusion will be dispelled quickly and painlessly!

(And you'll become one of the tragically hip!)

And I doubt anywill will take a really critical look at your freefall time-

>do i fall at 120 like i have been told or is it 109 like the book says . .

If you fall fast compared to people who normally do 4-way, you're probably falling at 120mph or faster. Borrow a protrack to see for sure.

I seriously doubt that anyone cares what table you use. Pick one and stick with it.
