Nice question:
What's the longest string for one move?
And how many different moves of that length exist?

Oops. I suddenly realize that the part up to the seventh single moves can be
modified into
1.? ? 2.**** **** 3.? ***** 4.**
This has a higher question mark density 3/7. Just a remark :)
There's one more challenge for everybody:
Find a mushikui sequence, so that you may replace the most number of
consecutive moves into question marks!
For example, the one above has two consecutive question marks.
