Very cool.  These detailed timings are very useful.

Might it be possible to include variance bars?  A few of the graphs
show your data structure faster than the list even for small N, and it
would be great to see if it is meaningfully faster in these cases (if
so, perhaps there are optimization possibilities for the current list
data structure).

A quite glance at your results shows a few more cases where the blist
faces problems, such no longer using Timsort, and so suffering in
performance for sorted/reversed cases.  That would be painful to give
up in the built-in list implementation.
