Burger winner geta a PPA B seeding

[stratus5]

PPA first corrects time to what it considers a top class GIRO field would do I.e. from 2:30 to 2:18 for the Burger.

 

It then calculates a difficulty rating for the event (beta) based on how the field did in the Argus 2010. The Burger 2010 gets a beta of 0.934 if I use my seeding result

 

So the Burgers winners PPA rating is (your time / adjusted winner's time - 1) / beta value and then expressed as a percentage, which is:

((150/138 -1) / 0.934) * 100 = 9.3 -> PPA B rating

 

Because the 2010 Argus was so windy the time gaps between the field were larger. I.e the slower riders are effected more than the faster riders. If the Argus had no wind, then the riders with a PPA seeding of 30 or less would all be closer together in time.

 

Currently the beta calculation sees all the riders as going too fast in PPA events compared to our Argus times, hence we are penalized with beta's of less than 1 too slow us down.

Which is fair

It is not a certainty that the beta is linear.

I dont have a problem with that. My problem is that the group you jump away from should be taken into consideration. I jumped away in G beat most of D E and F and would have come in the top half of C gets a rating of 33 which is I.

Everybody is affected. Those people you beat will get seedings lower than I.

 

The PPA base event was the Argus 2010. The wind made it very hard, so almost every other event is going to be seen as easier and penalized when they compare the spread of riders with a seeding index of less than 30.

 

Its tough for people who dont have older seedings (prior to the beta being introduced) to keep them in higher groups ... but if the 2011 Argus is very windy, then if the Burger winner cant make A, we may have very few riders left in A soon. Thos qualifying for A would all be in the elites.

 

I guess at the moment its almost impossible for anybody to improve their seeding, but it is possible to hang onto your current seeding.

Just remember that a PPA 'A' is not equal to an Argus 'A'. Your PPA seeding has very little to do with your Argus seeding!
