I'm very interested if you have an example that shows the (full) tree
outperforming the tinytree, because I have had difficulty finding such
examples myself. The tinytree usually wins because it is faster to
build, and uses less memory: in principle the full tree should be faster
if you keep it in memory and use it often enough to pay for the extra
build cost.

No, the key implementation in the two cases is identical.
