[NSRCA-discussion] New K Factors

[Stuart Chale]

Not sure if you are making a suggestion on the 4 pt and slow roll or saying that is your interpretation.  As listed in the catalog of maneuvers the 4 pt is a 3 and the slow is a 2.  Also no difference for inverted vs upright entry.  Not saying there has to be a difference but a thought...

Stu, I think any straight horizontal line maneuver should have its baseline a straight line at a Kfactor of 1. This should boost those maneuvers by a Kfactor of one and would seem to be more in line with norms. A 4 pt roll would then be a k4 and slow roll would then be a k3.  A full roll would then be a K2. At least this is how I would interpret the way it should be.



I also think the Kfactor ranges spelled out for each class need a closer look see. If I remember correctly a while ago I plugged in the new kfactors for the 2015 Masters sequence and it was lower than the designated range for Masters. I think it would be a good idea to plug in the numbers for at least the last 3 or so cycles of sequences to see if the ranges spelled out are reasonable. If the ranges aren’t closely examined it could have an unintended consequence of pushing the level of difficulty even higher than we are already at.

Subject: [NSRCA-discussion] New K Factors

I don't think I have seen any discussion on the list about the new
system for K factor designation so I thought I would start it off.

First before any questions or criticism this was a big job and I like
it, so thank you to the group that put this together.  The new K factors
run from 1-11 and are based on a basic maneuver with additional K's
added for added elements.  Using the old system there was always
questions when new maneuvers were added, Some if the K factor some seems
okay some high some low based on prior maneuvers. Sometimes it seems
arbitrary.

If you have not looked at the new documents, as I read it, the new K
factor is determined by adding a base K factor for the basic maneuver
and then looking at the added elements each with an assigned K addition.
The element with the highest K is added to the basic maneuver K factor
and then the rest of the element K factors are added up and divided by
two and added on.

For the most part this seems like it works, however I do not think that
all of the maneuvers are computed properly in the catalog maneuvers. If
I am reading correctly, the double I with knife edge flight did not half
the elements before adding them on.

Also when adding a basic knife edge element K factors are added for the
quarter roll in and the quarter roll out. Maneuvers with simple knife
edge flight in them would seem to get inflated K factors due to this.
The double I with knife edge flight is listed as a K of 10.  I think it
should be a K of 8 based on the intended calculation (I don't think the
dividing by 2 was done) .

A slow roll only has a K factor of 2. A four-point roll a K factor of
three.  In the current advanced sequence we have reduced the K factors
for these two maneuvers and increase the K factor total for the entire
sequence. This markedly reduces the importance of these two basic
maneuvers that often help to distinguish the better flyers.

No system is ever going to be perfect and I think this is a step in the
right direction. Just bringing these few points up to start a conversation.
