Actually, from just the Signal Strength, you can calculate the distance from your probe to the actual site (the real site, not the ghost signature) down to just a couple of meters.
We know how Signal Strength is calculated, and the only variables unknown once our results come back are distance to the deadspace and it's visibility (I've forgotten what Hoshi called it, but it's the equivalent of a ship's Radius/Sensor Strength). Anyway, since almost all the locations I've found have either a visibility of 0.1 (combat, profession) or 0.05 (mining), I use these to calculate a distance from probe to site, and it is accurate to within 50 meters or so. It's not especially useful, but it passes the time while waiting for the next 4.9 minutes to tick down.
--edit--
To get the best results, Hoshi's formula needs to be tweaked a little. The equation for calculating the effect of distance (ranging from a multiplier of 1 to 0.35) is actually e^(-(distance / max scan range)^2). The clue was the value for when you were at the maximum of your scan range (0.35) which was just too close to e^(-1) (0.367) to be a coincidence.
Also, the distance in AU is an AU = 149,597,870.691 km (not the rounded 150 that some of EVE's other systems use).
This makes sense. That's similar to the formula I discovered that CCP uses to calculate missile damage based upon target speed and missile explosion velocity. The difference being in that formula, they divide the two main variables instead of subtracting them.
Missile Damage * (Target Signature Radius / Missile Explosion Radius) * e^( -1 * (Target Velocity - Missile Explosion Velocity )^2 / (1500^2) ) = Final Missile Damage
CCP seems to really like using logarithmic functions a lot, most likely because it's a great system to do diminishing returns with and is fairly easy to tweak and adjust. I'm not a math major (actually I dropped out of college after failing Calc 3 times), so I'm not sure what that function you guys found looks like when graphed (wheres my graphing calc when I need it), but it certainly seems to fall into CCP's style of game mathematics.
