Differences in performace VTR v's SVD ?

[Hijack]

I am a happy chap today, my SVD arrived in the post, along with an aerotank.
I wanted the aerotank for my VTR, so changed it over with the iclear 30s that originally came with it, and put the 30s on the SVD.
Knowing that I like the 30s at 9.5 watts I set the SVD up the same and had a vape... ' no that's not right' so I tinkered...'na that's still not there'...tinker a bit more. Well without a tinker by tinker account finally got it the same as it was on the VTR, and found I needed it a full 2.5w higher to get the same results.
So im wondering why that is? is it inaccuracy's between the 2 mods in the way they display watts? Or is it more likely down to software and the chips used to regulate the power?
Im fairly new. only been vaping 4 months now, but do have a fairly good grasp of the way electronics work.
So can anybody tell me what they think the reason are for the quite different setup ive needed between the 2 devices using exactly the same tank?

I have a theory, but you probably won't like the answer.

The SVD is junk.

I base my theory on the large number of failures with the SVD. It is especially prone to button failures and randomly turning itself off for no reason. If you've got a fairly good grasp of how electronics work, then just consider this..... The wires inside your SVD are spliced together with a 3mm wide strip of tape, nothing more. No soldier, no connectors, just two wires twisted together and held with the smallest piece of tape possible.

probably because you have more voltage drop occuring inside your svd than in your vtr.

other possible explanation is your vtr is running in MEAN mode instead of RMS mode.

Really wow I'm surprised. Especially since it seems innokin listen to feedback about their products and tend to improve them over time.
e.g. Changing the orientation of the screen and +, -, buttons so it dosnt seem back to front anymore. and updating the software it uses so that the niggles that were apparent on early models is now fixed.
It seems strange that people saying 'it would be nice if you actually soldered the wires instead of using tape', hadn't got through to them yet.

Oh right I hadn't considered that 1 runs in MEAN and the other in RMS.

This is the most likely explanation.
