Thread: New speed formula...
However, I think devs have chosen something which is more easy. How did they come up with those constants?
To compare someone derived the forumla for armor resists in AS forum. he showed that the formula for resists is not using any exponential functions but a more simple formula. Like this:
% Resists = W1*60 + W2*ER
with W1 = Armor Points/10,000
W2 = (10,000 - Armor points)/10000
ER = Armor Points/200
(and W1+W1 always equal 1)

Which is a lot easier to understand equation than this taken from the curve:

You are probably right about the formula if you go from the data and calculate the function.

Tried some data for the new weapon speed and came up with:
actual speed=weapon speed*(0.5231+0.4769*2^(-speed/46))
Got a random deviation of at most 5e-3 meaning all numbers i found so far follow this furmula.
If you would care to see if this works or if it is faulting please post data for when it doesn't work and i will try to improve it.
Thanks in advance!
Is that (-speed) number the user's speed? If so, that's an interesting formula. I wonder where the numbers came from... If would drift down gradually as user speed increases, reaching a minimum of about 60% or so. This also seems to come pretty close to how myBase and User DPS numbers compare.

Yes, the - speed is your weapon+generic speed. Fits everything so far, except the carbineer core who used numbers he got when adding SEAs over the +25 cap.

The first feeling from looking at the numbers i got was that the formula should be:
actual speed= weapon speed*(0.5+0.5 * 2^(-your speed/50)) , that gave some residuals so i fitted a curve from there. I hope they didn't make it a polynomial.
btw, that armor formula simplifies to %=(22000A-A^2)/2000000, with a maximum of 60.5% at 11000 armor rating. If they hard cap it before that there wont be an issue...otherwise you can get negative effect from getting armor with higher stats.

Or of course... you can't extrapolate models, especially ones that are not based on...erm...physicallymotivated models :/
Well anyways agood way to validate any model as to how good it is is to try and predict numbers outside the area where your tests were made and see how good it works. That one was a polynomial and i get anallergic reaction (i am allergic to stupidity)even thinking the DEVs made it that simple.
