This is mostly just a copy/paste from PMs between Spekkio and I. Basically, we were revisiting the idea of using multiple MVs quickly on the same Helix. This EXACT same discussion was made in an earlier post on BG when SCH came out and someone first reached 65...

*************************
Let's just assume it's 10% of 50% for now (the 10% of full would be broken unless you cannot stack multiple MV on the same helix any longer). Maxed out, your MV would do x2 damage DoT with a 25% reduction in duration.
Helix ticks work like this usually... the first tick occurs 2 seconds after the spell lands, then every 10 seconds after for the duration of the spell. For example, say I land Cryohelix for 100 damage and the duration is 70 seconds...
Initial Damage... 2 seconds in... first tick... 12 seconds in... second tick... etc.etc.... 62 seconds in... 7th tick... 8 seconds of nothing... Helix Wears.
Now lets MV (no merits) and run the same thing.
Initial Damage... MV 1 second in... 2 seconds in... first tick double damage... 12 seconds in... 2nd tick double damage... 22 seconds in (tick)... 32 seconds in (tick)... 3 seconds of nothing... wears off (35 seconds total, 1/2 70).
So even with normal MV, you can increase your damage output with MV if you time it right and use it early (before the first tick occurring at second 2). In this situation I outlined, using MV would increase your damage by just an initial tick.
It's not really always '2 seconds in' but it's something close. I think it has to do with the game clock but never really looked closely at it. Sometimes it happens so fast it's like the first tick happened right when you nuked.

Now let's say the merit 5/5 gives you only 25% duration down. Same situation 100 damage cryohelix 70 second base duration. It now lasts 52.5 seconds with MW. If you use MV right when it lands and get full double damage ticks, the result is initial damage + 6 double damage ticks. To summarize damage outputs...
Normal Helix of 70 seconds = initial damage x8
Normal Helix of 70 seconds + MV = initial damage x9
Normal Helix of 70 seconds + MV5/5 = initial damage x13
It's about a 62-63% damage increase on your Helix after using a well timed MV 5/5. Pretty decent.
*********
So your question about stacking... Let's ASSUME you can stack as many as you want and that that first tick occurs at second #2. Easiest thing to see is see how many MVs you can do while still keeping duration above 2 seconds (to allow for tick, if it goes below, it's like the helix was on but wore off before tick occurred).
Again, 100 damage base, 70 sec base duration. All MVs hit before 2nd second (first tick). 3 Numbers listed as duration, MV# used, and "DoT damage per tick". Rounding down on seconds btw.
70 ; 0 ; 100
35 ; 1 ; 200
17 ; 2 ; 400
08 ; 3 ; 800
04 ; 4 ; 1600
02 ; 5 ; 3200
So you can only get off 5 MVs with no merits if you do it fast and perfectly before first tick occurs at 2nd second. This caps your damage at 32 times your initial damage. Now lets see with 5/5 MVs (75% duration)...
52 ; 0 ; 100
39 ; 1 ; 200
29 ; 2 ; 400
22 ; 3 ; 800
16 ; 4 ; 1600
12 ; 5 ; 3200
09 ; 6 ; 6400
07 ; 7 ; 12800
05 ; 8 ; 25600
03 ; 9 ; 51200
02 ; 10 ; 102400
02 ; 11 ; 204800
This caps at 2048 times your initial damage!... Theoredically, IF you can still stack at least 10-11 MVs, everyone had 5/5 merits in it, and you got all 10-11 off before that first time (~2 seconds, but remember it's still variable and not exact), you would produce 1 nasty DoT tick.
If you take perfect nuking conditions and SCH/BLM using Elemental Seal, Day and Weather bonus... you should be able to do at least 100 initial damage. Also, the duration I set for this 'test' was 70 sec, but it can vary from 60 to 80 I think. Anything over 100k I would consider a "1 shot kill". I think the new AV has 66k?
**********************
Couple things need to be tested with this idea...
1) Can MVs from different SCHs stack? We know it can for the same SCH (using COR to immediatley refilled - test done by Kohanacat back in Dec07). If it can, is there a limit?
2) Ensure that 5/5 MV merits does cause just a 25% duration decrease and not something else. Description points to this though.
3) Figure out how exactly that first 'tick' is applied on Helix. I think most SCHs that mess around with Helix know it's a bit random... sometimes that tick comes late, other times it's extremely fast and seemingly instant.
Thoughts?
