In-run profile

According to this material, I claim, that on every hill in beta-2, distance between B and E1 is too short, and between E1 and E2 too long.

In my opinion it should be changed.

[Bartek Palewicz]

That's 100% true! I completly agree with you, inrun should be longer and more flat.

[Martin Kafka]

On the contrary: by claiming that B - E1 is too short, isn't he suggesting, that the inrun should be more steep, not flat?

Anyway... I think Jussi knows what he's doing and he already changed the hill profiles a couple of times, first in Beta-2 after some Beta-1 issues and some further changes have been made after Beta-2 again. We'll have to wait and see what kind of result will emerge in the final version. Given he had all these documents at his disposal, I presume he worked with all that and took those hill data into consideration, among other things.
Also remember that each hill is different by its nature so the inrun table curve will vary according to their real-life "models": some will be naturally steeper and some naturally more flat.

[Jussi Koskela]

There might be some deviation in the transition curves, since the hill certificates which I am using as the basis to produce the profiles don't specify the exact form of the transition curve. Some older hills have/had circular transition curve (longer B-E1 distance) whereas more modern hills have a cubical parabola as a transition curve (shorter B-E1 distance). Other forms have also been used. Since I am missing this information I am defaulting to cubical parabola, which is the current recommendation for the hills.

[Jussi Koskela]

I just came up with a pretty good idea how to approximate the curvature better and will fix the in-run profiles accordingly.

nice can we expect the never ending inrun on the bischofshofen hill ?

Hey! I came up with that first!

[bulwa11]

lol I knew I heard that somewhere

Whatever, i mean inrun like Bischofshofen or like this:

Lol, that's from you.
BTW Great film!

Thanks. I'm glad you liked it.
I see what you mean... Unfortunately, there are not many hills like that these days as the beautiful old ones are being replaced with ugly, sterile, "factory-made" modern K-125/HS140 copies. A perfect example would be Ga-Pa. The new hills lack the spirit, the "magic" of the old ones. Today's competitions are safer, but also a lot less attractive for fans. I grew up with ski jumping of the late 90s, and 1999-2006 was the golden era for me. All the new rules, BMI stuff, wind/gate system, technology wars over suits etc. almost ruined the experience for me. I still watch every competition, but I'm not that enthusiastic about it anymore. It's just never gonna be the same. Well... I guess it's called progress :) 80s generation will probably feel similar about "their" era compared to the following decades, and the list goes on and on...
Now that you started it - I love the old profile of Predazzo, they were flying insanely high. Jussi managed to achieve similar effect for example in DSJ3's Argentina, I really hope there will be at least one representative of this phenomenon in DSJ4 :))

Almost all Jumpers Like Little bit Older Hills because it have more Pressure in Inrun
