Things look good. Thank you all for your input.
So the final formula is: Math + Mapping > me
But I am now able to reliably place measure segment length out while it is
being drawn (I am using the wz_jsgraphics library to draw a "rubber-band"
between the click start point and the mouse cursor).
I think you just solved the problem...I am using US Survey Feet as my
coordinate system.
So if this is truely the case and not a coincidence, then I don't have to
recalculate to feet because it's already there. I'll try that and see what I
get.
Thanks for the input!

It's either a pretty interesting coincidence that 23.529 / 77.196 =
0.3048, or else it's a units problem you've got (feet vs meters). 1
foot = 0.3048m.

Hmmm...something's not lining up right.
Here are my test values:
Start Point
x1 = 782968.222103
y1 = 1774880.116909
End Point
x2 = 783044.338
y2 = 1774867.244367
I used this formula in php:
$distance = sqrt(pow($x1 - $x2,2.0) + pow($y1 = $y2,2.0))
This gave me a value of 77.19671051057

This is the exact code that is being executed by the MeasureEuclideanDistance
API:
double CCoordinateSystem::MeasureEuclideanDistance(double x1, double y1, double
x2, double y2)
{
double distance = 0.0;

distance = ::sqrt(::pow(x1 - x2, 2.0) + ::pow(y1 - y2, 2.0));
