Re: 15 in 15: Efficient 15-bit Synthesis Project (34 SLs remain)

This is slightly off-topic, but I noticed that 13.238 can be tightened up slightly, reducing it from 7 to 6 gliders. This may improve some other syntheses:

Re: 15 in 15: Efficient 15-bit Synthesis Project (33 SLs remain)

Do you guys think that 15.786 can be taken off the list given an improvement on 13.82?
I'm pretty sure it's not on Catagolue (or just has 1 or 2 soups) and that seems like a somewhat plausible route.

That also gives 14.269 (EDIT: not 14.239) and 15.782 from 10. When and where was the improvement for 13.82 announced? I hadn't been aware of it.
Here it is from 13 (it could be 12 if the junk can be made from 3 gliders, rather than tub+glider):
