I have noticed that these 2 dimensions:
1) Saddle Tip to Brake Hood (Direct)
2) Saddle Tip to Brake Hood (Projected)
... on a road bike diaghram I create are almost always of equal length/measurement. I assume "Direct" is meant to represent a diagonal measure from the saddle tip across to either one of the brake hoods while "Projected" is a midway point between both brake hoods. IF my assumption is correct, then these two measures should always be different with the Direct being the longer one.
However I have found on most occassions they are identical but sometimes (and I have not figured out why) they are different and closer in measurement to what I assume they represent.
Is this an error in the software or do they represent something else?
