Sometimes I just miss a "like" button

Great pictures.  That plunger was almost all the way out, did you happen to measure it?  How many miles did it take to get that way?  I don't know how far out the new hole is but it looks like the chain must have enough slack so that the plunger is almost out of there before you can use that new hole.  Somewhere I think someone wrote that on new bikes the plunger protrudes 5mm to the shoulder, you're probably tighter than that now, hard to scale from a picture.  Wonder if the second hole could be a little closer.  Anyway in your case it was perfect, must feel good to get that done.  The Verslavy mod really makes the most of a chain.

AHH, saved just in the nick of time, only an hour's work, and now ready for another 11,000 miles..

[LIKE] indeed  

Thanks for sharing the info.  I think I will plan on checking mine at some point before 10,000 miles.  The chart Verslagen1 provided the link for indicates new and old adjusters.  The ones marked new seemed to have less extension for the miles but the data is really all over the place, many variables.
