What steps will reproduce the problem?
1.use a test dummy to cast arcane blast with the slow effect speced
2.watch DPS drop as the slow effect lingers
3.

What is the expected output? What do you see instead?
I expected to see the same DPS from recount as from skada. What I saw instead was that slow effect(no damage debuff) would cause an extra 15 secs of 0 dps tacked on. Specificly that my DPS was being dropped from 23k(recount) to 14k(skada). The damage dpne was perfectly the same, so the time range it was using is being extended by a your dot calculations on a non-dot effect.

What version of the product are you using?
1.3-11

Do you have an error log of what happened?
No but it is easily recreatable

Please provide any additional information below.
I had never heard of Skada before but i can see how it can be more accurate than recount. However this is a huge bug for Arcane Mages and you may want to investigate other debuffs that act like dots but are not dots.
