Lol, had soot myself in the tummy with my weekly shot of bydureon, 
because I've been a DM-II for about 40 years, and to put on my morning 
pot of coffee before replying.

I am slightly less well organzized, if its multi-page I staple it 
together and put it in the action pile. Searching it is a bit of a chore 
and eventually the pile has an avalanch and gets sorted a bit IF I pick 
it. Otherwise it moves to the round file a handfull at a time. Once I've 
committed it to wet ram enough times it usually safe to ditch it. At 86, 
I find I have to reread it more times, something I didn't have to do 70 
years ago.  One could say I've reached that age where I don't buy green 
banannas. Theres a pacemaker to replace mine that was failing 2 years 
ago, a bunch of stents and a new valve a year ago trying to keep it 
going at 30% or I'd be history quietly forgotten already.  They took a 
look at their work in January and told me to come back in another year, 
indicating confidence in their work. We'll see. In any event, Its been a 
wild ride so far. I've got a bigger collection of BTDT's than the 
average bear.  I've gotten the impression that you have a longer list 
too.

Take care & stay well, Nik.

Cheers, Gene Heskett

202,200 for the outside spline and the flex gear is 200.  In this situation
- the 202 tooth spline is stationary to the stepper.  The 200 tooth outside
spline is mounted to the faceplate.  In this layout - the ratio apears to
be 101:1

In this situation the stepper motor and the face plate spin the same
direction.

With the same set of outside spines swapped - the ratio is 100:1

I am sure Andy can explain it.  It doesn't make sense to me.

It's because there is an extra 1-tooth movement of the spline with the
moving gear.

Expected I think Sam. The difference in speeds is because the stationary 
gear is the reference. 202/200=1.01 but 200/202=0.9900990099, is not .99 
flat. The reciprocal's should match and do though.

But the rest of the proof is above my pay grade, the 8 years I did spend 
in school was blessed with a male math teacher far more interested in 
what was in the girls panties than in actually teaching math.

He eventually disappeared in the middle of the night, it was rumored at 
the insistance of a loaded 12 gauge held by an un-named girls father. I 
was out of town, working at a hardware store fixing tv's at the time. 
And driving the stores pickup on service calls sickly bird since I 
wasn't old enough to get a drivers license yet.

Small towns, pop 270 or so on Saturday nights, tend to solve such 
problems w/o involving the county sheriff. I heard about 4th hand, that 
he did get arrested for similar reasons a year or so later in another 
small town.

Using the math from that link below 
(202-200)/200=0.01 ==> inverted is 100:1.

Done the other way...  If that's possible then
(202-200)/202 = 0.0099009900... ==> inverted is 101:1

no - one way (current way with the 200 spline stationary with the stepper)
the stepper goes the same direction as the face plate.  The with the
outside splines swapped - stepper goes the opposite direction of the face
plate.
