These crafts are actually quite fun but the difficulty is trivial. They aren't good for any sort of competition especially as there are no limits to how many you can submit.

I tracked four sets of around 15 synths and each time it was 14 at max collectability and 1 botch at 5.5-6k collectability.

They're also possibly balanced for min craft/control as I usually overshoot the requirements by quite a wide margin.
