Great info!
Being a little bit of a numbers geek myself, I did a bit of the same, and my model so far (with a smaller sample size than yours, in the hundred(s)) is:
- gold gear 20%
- 50-piece purple gear 25%
- blue gear 33%
- green gear 50%
For instance, simming the node 7D (10 energy) for 250 times gave me 66 stun cuffs (~25%), 90 of the blue thing (36%) and 113 of the green one (~50%)
I've also done a monstrous spreadsheet with what gear can be obtained where, what are the bargains and the rip-offs (per store). (

Feel free to use / copy it (and redistribute it, just add my name somewhere as co-author).
I've also gathered the actual demand for gear (it doesn't matter to me if Carbanti Mk4s are overpriced, since no one needs them), but haven't found an elegant way to combine both worlds. Well in the end, it all boils down to one simple rule: You need 5000 stun cuff pieces, so get 'em any way you can.
