Mixer Level to dB Conversion - and more

Originally included in my response to [Db`s or 0-127] - DJSTARSKI.
Thought I'd post it again here under a more descriptive subject.
Some interesting data I've collected over the last few weeks, just trying to understand the Mixer and audio levels and how audio is moved around in Reason.

WARNING: too much information mode = ON
(do I have a lot of time on my hands or what?!?)

Mixer Faders (and Master Fader) are Unity at 100 (or -7dB from clipping)

Mixer Fader (1-127) levels to dB:
127 = 0dB
123 = -1dB
119 = -2dB
115 = -3dB
111 = -4dB
106 = -5dB
104 = -6dB
100 = -7dB
97 = -8dB
93 = -9dB
83 = -12dB
72 = -15dB
64 = -18dB

What's weird is that the NN-19 sampler levels don't match these. They are:
127 = 0dB
123 = -3dB
112 = -6dB
100 = -9dB

Mixer Sends are Unity at:
Mono send = 79
Stereo send = 100
(since sereo aux sends follow channel panning, when panned hard left or right unity is at a send level of 79)

Mixer Meters: (from top to bottom)
(all levels rounded to nearest 0.5dB)
Top 'LED' (orange) = -1dB
2nd (orange) = -3.5dB
3rd (orange) = -6.0dB
4th (orange) = -8.5dB
5th (yellow) = -10.5dB
6th (yellow) = -13.0dB
7th (yellow) = -15.5dB
8th (yellow) = -17.5dB
9th (green) = -20.0dB
10th (green) = -22.5dB
11th (green) = -25.0dB
12th (green) = -27.3dB
13th (green) = -29.5dB
14th (green) = -32.0dB
15th (green) = -34.5dB
16th (green) = -36.5dB
17th (green) = -38.5dB
18th (green) = -41.5dB
19th (green) = -44.0dB
20th (green) = -45.5dB
