Same as David wrote: the last two cut (for 326) was very hard to find, for me, too. And before the 2 off, I was around 250+, for a while, as well.
Very nice one!
After playing all the other twinnings this was a nice subversion/mental trickery. 326 seemed far away for a while. When i finally saw what needed to be done I went right to 326
That last 2-cut was really difficult. Excellent job optimizing this, dgriff, and nice work putting this Twinning together, Hem! It's very challenging to think through the correct approach for optimizing this - I was at 340 for a long time.
