If You're clicking 2 different abilities buttons one instantly after another then second ability wont fire. That second click will not be recognised by the game until ~0,4 sec before abilities global coodown end , when registering for next attack is starting.

As for hitting with onslaught , assasins will , suprise attack and 2 executioners all within around 3 seconds it's possible even without animation cancelling. Global cooldown for abilities is 0,9 seconds. Chanelled and cast time abilities start their global cooldown counting when You click them. So with onslaught having 0,4 sec cast time when it hits target then onslaughts owner is already after 0,4 sec of global cooldown counting so he is just 0,5 sec away from being able to use next ability. Assuming that perfect weaving was used and we start counting timer after onslaught hit it'll look something like that :
0.0 sec - onslaught hit
0.5 sec - assasins will hit
1,4 sec - suprise attack hit
2,3 sec - 1st executioner hit
3,2 sec 2nd executioner hit

If we would begin counting when onclaughts animation starts it would just go up to 3,6 seconds. So as You can see hitting all those 5 attacks within ~3 seconds is possible and there is no animation cancelling needed for that. You just need to click fast and properly.

Skills have 0,9 sec global cooldown. Even add on designed to show global cooldowns have 900 ms refresh ratio https://www.esoui.com/downloads/info2322-GlobalCooldownGCDBar.html . It's also not coincidene that You can get sometimes ability cast ratio over 1.0 . No onslaught do not have different global cooldown. It's just hits enemy 0,4 sec after using it because it have a cast time and it cannot be speed up so You'll always get hit atleast 0,4 sec after enemy used it which means global cooldown left to use another ability at this point is 0,5 sec because 0,4+0,5=0,9.

I assumed that somebody would start combo with onslaught to maximize DPS due to 100% penetration he/she will get for next attacks and overal shorter time of whole combo but even without that whole combo would get just 0,4 sec longer if You wouldn't start from onslaught. Death recap do not always show abilities that killed You in proper row especially if quick combo killed You. And no You do not need animation cancelling to perform what I've described in my first post. Duration of animations doesnt matter when we're talking about instant cast abilities. Even if executioner would have animation longer then 0,9 sec it would slightly clip itself out at the end after global cooldown is over and You're using next ability. So overall time of properly executed combo in perfect conditions is 3,2 sec and even with delays caused by lag and human error You can stll keep it under 4 seconds. And that is not even fastest combo possible. There are combos in the game where You can get hit by 4 abilities and light/medium attacks inbetween in slightly more then one second (dizzying into medium attack+onslaught into blastbones and la+executioner)

And sorry but Your method of measuring time by counting to three in Your head is not the greatest method I've seen. Using combat log for that would be reccomended even though it also have it downsides it's still far better then counting time in Your head.

Can you get us a CMX log with skill chained at 0.9 interval ? pretty sure it is indeed 1 sec and that add-on that use 0.9 do so to help queuing before the end of the CD.

CMX is measuring it on client side. That is why in CMX combat log very often You'll see different intervals between abilities casts sometimes under 1 second and sometimes above because it measures how Your client registered them. In that context CMX is not 100% reliable because we're talking here about very small time margins. But even in CMX You can perform longer parses where Your ability cast ratio will be above 1.0.
