im pretty sure your wrong. only for cti 500 is max (current + max)/2
for cti of 1 it does return close to max value
ex.
current 1500 max 3000 cti 1
returns 2994.0299
theres a gap value thats multiplied against and this creates an add value that closes the gap.
so it does pass your second test. i tested all this myself in a similar fashion to ensure it reached near max. ill have to post the google sheet later.
btw. we did a simple fix for values over or at max. we just returm current.
man... all that talk about my method, and a 1500/3000 on sim3 is 2250 (i.e. (current + max)/2)not sure on this one
the problem with all this code, is we need to figure it out, because Splinterz is on the cusp of his next release, and you keep getting my formula wrong... dogging it and all is frustrating when your saying incorrect things about it.
I don't really care what formula we use, but it irks me when you say it's broken, but you point out things that aren't broken.
so it makes it harder for Splinterz to figure out what goes into v20.
I'm working on getting a comparison between your sim3 and mine right now, going to graph it and display it.
update:
now it's my turn.
yours and mine seem to be on par with each other... until you get to 1 CTI, then what happens?
your's goes negative... in all fairness though, it only does it for 1, and not 2...
This all started because I want to feed the values back into the bins (which I now firmly believe can be done safely), so I came up with a formula I understood in order to do so, but now I understand how att_sim works... so I don't think it matters if we feed it in or not, it just scales things back down to the normal bin frequencys (Splinterz concern all along was your formula was producing really large #'s... which to be honest, could have just been re-merged with the original value, which I was doing... so like I said, I don't care what value we use).
here's sim3 vs my code, and to be honest, they produce VERY SIMILAR NUMBERS, yet mine produces numbers that work with any range of CTI 1 to 1000+... to be honest, the code is in your credit, I had no idea how to reduce the scale, but it's more workable, and doesn't need to cap any values to work

we're honestly crying over small differences... I'm just going to chock it up to you not following my formula through all the way. However, you seem to be quite aloof to reading about things you have an understanding of (I'm choosing my words carefully here)...
which means you miss the details (hence the comment on reading/responding to emails).
I'm saying here, that my formula does account for low CTI's, as you can see, as well as high CTI's...
so what's the diff. The only reason I created it was to feed it back into the frequency bins... I know what mine's doing, yours is doing some area measurements under some sort of curve that I don't get, but they do the same thing in the end, graph it any which way you want, and give some honest feedback (please, lets just comment and be honest in the shortcomings).
question?
BTW, in case you didn't notice this yourself, your graphs for sim3 had 2 intervals where they were linear: before the cap and after the cap.
link please?
Hey Maklak...
I don't want you thinking I'm hating on you, I'm just trying to figure this shit out. If we can't implement it without not knowing how it works, it's like magic to us...
I've been rereading, and you posted this
sim3 gives you the predicted average attribute value during some some hypothethical gain. If you don't hit a cap, it returns "att + att_sim/2" (the formulas it uses do exactly this, except are more complex to handle the second part. After you hit the cap, value returned by sim3 is between "(att_cap+att)/2" and "att_cap". It increases with att_sim at the speed of "x/(1+x)" (If you really want me to, I can derive the formula for this).
which looks quite similar to my (current + max)/2 concept...
so I think we're hitting on the same things, maybe you can explain SUPER LAMEN terms how what I conjured compares with yours (I know you don't owe us that, but if you present it, then Splinterz will understand, and be that much better to make his decision on v20!)...
Update:
Here's a pic of it graphed (sorted by current smallest to largest, cap smallest to largest, cti largest to smallest)
