FitBit Surge gypped me on steps so I added a Zip

I do most of all of my daily steps on my LifeSpan Treadmill Desk DT-5. Since I am working on this desk all day, I am oftentimes leaning over a little, putting pressure on the built-in arms pads with my arms, and typing, typing, typing, isolating my movements so that I can focus on writing emails, contracts, proposals and hours client service work.  

 It all used to work just fine, until recently. In the last months my FitBit Surge stopped logging my sleep accurately and it also never recorded more than 1,700-4,500 or so steps-day even though I've been working on the treadmill for hours all day long.

So, I assumed that FitBit changed its algorithm.

For a while these updates were good as my FitBit stopped recording my motorcycle trips as steps.

But now, my wrist-mounted FitBit Surge doesn't record my treadmill steps well at all.

So, I went onto eBay and bought a brand new FitBit Zip for super-cheap, added it to my FitBit devices (apparently the FitBit app can support multiple devices now -- great news!), and all of a sudden I have so many more steps (and it's not even ten AM this morning).  

So, I have things sorted.

PS: if FitBit reads this, yes, I have already done a couple hard restarts on the Surge it and it hasn't helped the surge at all.
