Nice. Is the foolproof way to just add one link at a time until it works on big chainring/cog and small chainring/cog? It's a triple chainset, BTW.

There are different methods but I just use the big ring / largest cog routine as below. Has always worked for me - including the modification for 1x set-ups:

Adding one link at a time until it is right means you could end up with more joins than necessary which I try to avoid, and also you’d end up with your multiple joins at the same part of the chain.
Having said that 2 joins is fine. I have done this on the Surly (1 quick link and 1 joining rivet, separated by half a dozen links) as standard length chains weren’t long enough for 1x11 + Trucker chainstays.

Set the gearing to the big cog at the back, then open the quicklink without taking the chain off and move the chain round until both ends are sitting on the big ring's teeth, with some sort of gap in between. The rear mech will fight you, so an assistant or a velcro strap may be useful.
Work out what the smallest gap is you can have without the rear mech looking over extended. Add that many links.
A chain with two quicklinks is not really any more likely to fail than one.

It'll be fine.
