I'm glowing.  :-)

It seems to me that ETC is much more effective in an MTD(f) search than
in a PVS search.  I think most MTDers use ETC.

Another important factor might be the speed of the engine.  It makes
sense that a sub-200 kN/s-engine like mine will benefit more from ETC
than a fast engine like yours.
