Brian,
What is a "touch" ?
Is it a cross, a real touch or an approximate touch ?
The real touch is quite rare, C should be exactly equal to the LINE
value.
The accumulated crosses are
Cum(Cross(C,LINE) + Cross(LINE,C))
A true "touch" would require C==LINE and this is quite rare to occur.
Anyway, the accumulated touches would be Cum(C==LINE).
Another, more realistic idea of touch is the C "near" the LINE.
You could define "near" [less than 1% or less than 0.1% etc] and then
add these generalized touches.
PERC=0.01;
near=C<(1+PERC)*LINE AND C>(1-PERC)*LINE;
touches=Cum(near);
