Needles to say I'm greatly discouraged.
You had a 71.5% desynth success change, right? 40% is unlucky, but not that unlucky. Sounds like you broke 20 where the average was 15. If you wanted to reduce that chance and had a giant number of things to desynth all at once, you might have considered using HQ Tinker's Calm, and possibly HQ Bacon Broth as well. Together, you would have had half the fail rate and wound up with 10 more successful desynths on average.

As people have pointed out on this thread and others, spectacles aren't the best method of getting MCDs anymore. Tools have a much higher yield than specs. For GSM, you could use Artisan's Needles.
