You'd need to document the first paragraph of this, but I agree that the Nolot
test does show the tactical power of DT. I ran some of those positions for
several days and didn't find solutions that DT found much more quickly.
This is not true of all of the Nolot positions, however, but then again DT isn't
*that* fast.
Let's have another thread about the Nolot positions.
Here are my results as of now:
DT Ferret
4x450
------ ------
1 6hr
2 2min 31sec
3
4 2.5hr
5 2hr
6
7 6hr
8
9 9min
10 2min 11sec
11 5min 48sec
I ran mine for 3 minutes per position. As of this moment I am starting a run at
two hours per position. Another version got position one in 1hr23min, we'll see
how well this one does. I'll fill the chart in tomorrow. If either of you
would like to run any of these, go for it.
Scoring is done for "find and hold", meaning your time stars from the initial
fail-high, and you get no credit if you switch to some other move before the end
of the test.
