uhm, this ain't the dragrace list, dude.  For most of us the throttle
has many more positions than ON and OFF.  Top fuelers run at WOT, near
constant load and speed i believe.  They can't benefit from spark
advance of any form.  My 68 Camaro's 350 on the other hand sees full throttle
at any speed between 1800 RPM and 5500RPM...  and theres a significant
difference in MBT timing for 1800RPM WOT and 5500RPM WOT on my motor.
If I was just worried about WOT, tho, good ole mechanical advance would
do everything I need.  But I spend a lot more time at part throttle on
the street than I do at WOT.  And the difference between MBT timing
at 1800RPM idling and 1800RPM WOT is MUCH larger than the difference
between MBT timing at 1800RPM WOT and 5500RPM WOT.  SO it probably won't
help your quarter mile...  but it'll sure help your idle, fuel economy,
streetability, etc.
