Today the wind hasn't picked up to "Oh my God" yet so I will take a ride and test out my shifting on the Eddy Merckx. The only thing I'm worried about is overshifting in the big ring and throwing the chain off.

You know, there is a limit screw on your front derailleur that prevents you from throwing the chain off. You might want to adjust that.

The chain now has three quick links in it and that isn't a good omen but we'll see.

How does that even happen? If it were a Shimano chain, at least you could use pins so you didn't have a bunch of dopey quick links.

My Habanero does not throw chains off big ring and normally if set correct this should not happen. However sometimes as mentioned J I believe, the small ring will dump the chain. It has not happened to be ever on the Habanero in 25,000 miles but my Wilier would still sometimes dump the small ring. I installed chain catcher and that ended if for good a beautiful little gadget that does not weight anything really.
If you set the front derailleur up exactly right it won't overshift the large ring. But in order to have absolutely dead quiet shifting with no dragging at all in any cog, you have to set it up exactly correct. Then if the limit screws bed in tighter, which they normally do, you have to reset the limit screws. Of course that is AFTER your ride or perhaps during it if you want to stop and reset the limit screws.
The limit screws have nothing to do with adjusting in an indexed front system. They are safety measures for knuckleheads.
What are you talking about Lou? You use Shimano don't you? Campy doesn't work that way. If you don't limit the motion of the front derailleur with the limit screws it can throw the chain all the way out to the pedal. Tell me why the **** there are limit screws if you think that somehow the chain would never come off the chain rings? ALL front derailleurs have limit screws on them and if you believe that you don't need them you are the knucklehead.
I said with an indexed system. You are right about Campy. That is a ratchet system. I use both BTW so I know what I’m talking about.

Forgot to tell. A Campy front shifter has 11 clicks IIRC. Shifting between the two chainrings only needs 3 or 4 clicks. They can be anywhere in the range of 11. This said I think it is not wise to limit the movement during adjusting with the limit screws. In that case it can be just before or after a click. Adjust the FD with the barrel adjuster using the full 3 or 4 clicks and then set the limit screws preventing that you move the FD beyond that full click; upper and lower. What I always do with Campy is set the lower limit screw before attaching the cable, attach the cable as tight as possible without moving the FD, move away the limit screws, fine adjust with the barrel adjuster and at last set the limit screws so that they just not touch their stop at the outer click positions of the adjusted FD. How many people start fiddling with the limit screws at the moment shifting gets bad? Those are the knuckleheads who don't understand how it works.
