DET is a horrible stat, and until someone properly math-s it out for SMN, I personally value SS more than DET. More up-time on our DoTs, faster SF/Tri-Disaster casts, passive buff, etc.

Not to mention other weights won't be valid for long, because DET has a value based on each ability used.

Not to mention it's also been said that DET has either no, or very very low scaling for any DoTs(or the DoT portion of skills).

One of those posts said a SMN tested gains of only +1 per tick by adding 30 DET. With the damage I do that'd be slightly more than 1% more damage, which is similar to (actually slightly greater than) the gains from adding the same amount of CRIT points (+0.98%) according to Valk's calculator. The gains in both cases are slight, and personally I feel DET is undervalued by most people.

That's less than the gains of crit.
26-28(I forgot if it's 13 or 14 crit) crit = 2% crit = 1% DPS increase.

Not to mention DET comes in lower amounts than SS/crit.

My bio hits for 96(low), 106(high). +1 damage is barely above (.0104), and barely below (.0094). Which averages out to just below a 1% increase(.0099).

At the steep cost of 30 DET, of which I could get a lot more crit, which scales better.

As a side note, the post says +1 damage. Does not specify if it's per tick, or total. I would assume per tick, as you have, since it'd be hard to test +1 damage total, although that would make sense with the scaling of other abilities.

Rei with synapse reported that with SMN dots a 30 det increase gave him 1 additional damage, so either there weren't enough samples (which isn't usually the case) or there is some minor scaling going on.

If you read earlier, Eein said this about BRD DoTs:

I sat on the dummy for 5 minutes, got the same min-max values with 202 det and 246 det at the same dex value.

Valk's testing was flawed, as well, which brought the admin of chocobro to test DET and find how it's flawed. One of the flaws being scaling towards DoTs as compared to other abilities, and the fact that each ability has it's own scaling(which I would assume is based off of potency. The chart I posted, bloodletter/heavy shot have same scaling, whereas VB takes quite a bit more DET).
