I see promise here. This is a fresh take on the logo. I do see room for improvement on the color palette. The current choices are a bit too drab. Also, while the pie graph for an "e" is an interesting concept, I think you need to start with an "e" and make it look like a pie graph. As it is, it's just a pie graph inserted between "M" and "t." If you can somehow make that pie graph have the feel of an "e," then we may be on to something. Good start!
Paull - can you try some iterations on Entry #63 ? Specifically, breaking the two items apart? try one with the "i" like you have it in "spring" as a spring, but the "e" in metrics is just a standard e. And then try another where the "i" in spring is just a standard i, and keep the "e" as the pie chart "e". I think having both elements together is too much, so I just wanted to see them separated out.
Make the "e" in metrics the same size as the other letters in metrics - so the top and bottom of the e should line up with the top and bottom of the c.
I'm not crazy about the fonts - are you up for trying some other fonts for both Spring and Metrics? I think your fonts from #1 were better than #75, but there may be even better font choices that that as well.
For that matter - I do like "I" in #74, but I guess it may be the font of "spring" in #74 that I don't like. I'm not sure if there is another font that may still work with that I - but it may be worth exploring. I think it has promise - it just doesn't feel quite right as it is.
