This may have more to do with the saddle itself or the angle of the saddle.
Probably, I am in fact looking for a suitable saddle to hopefully allow the next 4 months to go by pain free before I get my hands on an Ergon SM3 saddle.

It may give you more leg power too as it is the Time Trial position. It is also known to stress the knees more. If you are young, you probably don't have to worry about it.
My pedal's platform is supposedly angled 6 degrees from horizontal and is "anatomically optimal for maximum efficiency, providing Varus correction. Aligns the biomechanics of the leg (hip, knee, foot). Prevents knee complaints and foot numbness." I've been using it since the Sydney Spring Cycle and not had any complaints, whether that's because I'm not a MAMIL yet I wouldn't know.

XC Fit
Standover Height Range 31.4 - 32.1 inches
Virtual Top Tube Length 22.9 - 23.3 inches (average 58.7cm, so medium size)
Stem Length 9.6 - 11.2 cm (average 10.4cm, so 10 or 11cm)
BB-Saddle Position 72.5 - 74.0cm (average 73.25cm)
Saddle-Handlebar 52.8 - 54.4 cm (This is just a guide for weight distribution)
will see whether any of this makes sense when I measure the bike come daylight.
Measurements off my bike:
XC Fit
Standover Height Range 31.4 - 32.1 inches
[29", not really important?]
Virtual Top Tube Length 22.9 - 23.3 inches
[46cm/18"...?]
Stem Length 9.6 - 11.2 cm
[11cm, so about normal]
BB-Saddle Position 72.5 - 74.0cm
[69cm, a bit shorter..]
Saddle-Handlebar 52.8 - 54.4 cm
[47cm, so my COG is further forward on the bike to account for the afformentioned hills]
It may also be of interest that my crank arms are 180mm.
What's it all mean? Should I be sitting a lot further back and a bit higher? With my current saddle position I'm just about already standing with my legs straight up when I have my heels on the pedal and although my arms could still reach a bit longer if needed I find that it currently allows me a comfortable bent arm position when pedalling upright and also works well when I'm pedalling over the handlebars.
