Hello, @alvarotrigo Can you say your browser, os version and device model? And please try to repeat bug on textarea in the bottom of http://promo.github.io/wheel-indicator/ and send here log with deltas from it.
var deltasArr = [-6,-6,-18,-12,-12,-18,-18,-18,-21,-12,-30,-9,-18,-24,-18,-30,-27,-30,-24,-114,-30,-24,-24,-24,-30,-21,-21,-27,-21,-24,-24,-21,-24,-21,-21,-21,-21,-27,-21,-24,-27,-39,-45,-42,-62,-62,-72,-66,-81,-96,-84,-51,-90,-60,-81,-57,-48,-39,-30,-27,-27,-21,-15,-12,-9,-9,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,3,-3,3,3,3,3,3,3,3,3];

@alvarotrigo On the video looks like you did two movements, one small in begin, and then second long. It's not a bug, also we can't detect such situations.
About log. it's very strange sequence for one movement. Algorithms detected ['up', 'up', 'down']. It really was one movement?

It was only one movement. None stop. Slow scrolling at first and accelerating at the end.
Here you have another log:
var deltasArr = [-3,-3,-6,-3,-9,-9,-6,-12,-6,-9,-9,-9,-6,-9,-6,-6,-6,-6,-27,-9,-3,-9,-6,-6,-6,-6,-6,-6,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3,-6,-3,-6,-9,-9,-12,-12,-15,-21,-24,-30,-24,-33,-30,-42,-54,-36,-51,-51,-66,-62,-69,-72,-75,-78,-75,-60,-57,-62,-62,-57,-51,-51,-48,-45,-120,-27,-39,-21,-27,-18,-21,-6,-12,-15,-9,-9,-12,-6,-6,-6,-9,-6,-6,-6,-6,-3,-6,-3,-3,-3,-3,-3,-3,3,-3,-3,-3,3,-3,-3,-3,-3,3,3,3,3,3];
It enters in the isStopped
condition here AND also in the is not accelerating one here.
Here you can play with it in the fiddle, you'll see in the right the delta values and a line whenever a new movement is detected when it shouldn't. http://jsfiddle.net/obLrdpLn/1/
Something like:

Sometimes even 3 scrolls were detected with a single swipe:
var deltasArr = [-3,-12,-9,-12,-12,-12,-12,-24,-24,-21,-33,-30,-234,-33,-48,-45,-42,-45,-48,-60,-45,-81,-62,-57,-54,-81,-87,-75,-81,-108,-117,-93,-117,-111,-111,-111,-60,-90,-204,-204,-204,-195,-192,-189,-183,-177,-159,-144,-135,-123,-108,-102,-90,-84,-78,-72,-62,-57,-54,-48,-45,-42,-39,-36,-33,-30,-27,-24,-24,-21,-18,-18,-15,-15,-15,-12,-12,-12,-9,-9,-6,-6,-6,-6,-3,-3,-3,-3,-3,-3,-3,-3,-3,-3];
I attach another video where you can clearly see I'm only swiping once and how two "up" arrows are being generated in your site. http://tinypic.com/player.php?v=34orngw%3E&s=8#.VYWXmxNViko
What about using an average of the last scrolling values as a check instead of the exact value of the last 3 scrolls? (which as you saw, might lead to problems)
Take a look at the implementation of fullPage.js to see if it is accelerating or not.
@alvarotrigo hello. Sorry, but right now we don't have enough time for research the problem. Soon we will try to come back to this.
@alvarotrigo we have written new beta (works only with chrome yet). Check it out and give feedback please.
Hi @f0rmat1k , it seems it has improved for kinetic scrolling trackpads, but now it reports two scroll for normal scroll mouses when the 1st and the 2nd scroll are not very close to each other. I noticed it when scrolling normally.
It still sometimes trigger 2 times for me too with a magic mouse.
@AntoineBoulanger Ye, there is a small chance that double event occur. But we don't know yet what to do :).
First of all, congratulations for the script! It seems to work quite well in general.
I found a couple of small problems, this is one of them as you can see in the video: https://vimeo.com/131253387
