Veloce and Record ergo shifter question.divve

Please bear with me.....

With the chain in one of the smaller sprockets in the rear, not turning the pedals, you softly push the large shift lever inward without actually making a complete shift, let lose, watch the derailleur return to its original position. Now, softly push down on the thumb paddle without actually shifting again, do you see the derailleur move another millimeter or so farther outward?

I'd like to find out whether there's a difference in the detent position of the Ergo shifters between moving the derailleur inward and outward. Thanks.

I pushed the lever to shift to a lower gear but before it clicks it moves up and stays half way then when I hit the thumb lever it goes back down.
I think there is a ratchet inside and it is wanted to grab when it reaches the top ot the ramp but it seems to grab until it hits the top. Hitting the thumb lever releases the ratchet. Have not got to take one apart yet to see how it works, but I can't wait. Hopefully some lucky guy on a club ride will have his fail so I can offer to rebuild it for free! Then I will fully understand how it works.

Thanks for the help. Now at least I know that my Ergo isn't acting weird. I haven't seen the complete insides yet either, but I think the ratchet consists of some sort of cog like wheels and "G" shaped springs for indexing. If that's true it also explains the relative lack of accuracy in the system. Also, if you pull on a shift cable hard enough it will loosen by one index a time. Pretty much confirming there's no saw toothed wheel and locking pawl.
