To the point that GPS could not be used for precision approaches. On a GPS approach, the GPS altimeter could be 100-200 feet off from the aircraft's aneroid altimeter. Since a precision approach such as a cat 3 ILS, approach has minimums of under 200 feet, GPS was unsafe. Today, these errors are generally less than 25 feet so approach minimums have been lowered. While I get your point about slope angle, this improved vertical position accuracy also applies to riding applications and as a result, speed calculations are much more accurate than they were 10 years ago. In any case, your cell phone GPS is likely to be within 2-3 MPH of accurate.

In addition, all the apps run different algorithms, none of which are calibrated to each other so comparison is worthless?

i would trust the reading of a slopeside cop with a radar gun,kinda... gps speeds seem inaccurate, mostly exaggerated

if you are scaring yourself a bit, then you are going fast enough

Speed isn't very important I feel. Whats the fun in bombing runs? Maybe if your just trying to rack up the vertical or racing a group of your friends then yea. Like everyone else said, the more experience and confidence you obtain, speed will just come naturally.

The Real test isn't bombing groomers but shredding the trees at high speed.

If you want to go really fast I'd suggest grabbing a pair of skis.

There are a couple of places on Seymour where you want to get up as much speed as possible to make it past the flats or up a hill on the other side. Baker has some of the same. It's not speed for its own sake, but I remember the first couple of times coming out of the Brockton area where it was a toss-up whether I was going to make it to the end of the bombing stretch in one piece. So even if you don't like bombing, sometimes you have to be able to.

ALL the back and reds in my home resort have at least one such flat stretch or chairlift stations on elevations. It was designed for skiers with poles... Some friends avoid the resort becaus of this. You either learn to straight line or you walk. On every run. I still don't make it over all elevations...
