Well, for those curious, here are the results:
Some notes on my method:
Realforce 104 straight out of the box and plugged into my PC.
I set the force gauge to freeze on the peak measurement and zero'd it after each test.
I took extra care to position the test rod in the centre of the keycap and slowly pressed the key down until it actuated and the keypress was registered (note: not bottoming it out)
I actually tested each key probably about 6 or 7 times before doing the three consecutive measurements - I noticed that not hitting the key right in the centre really varies the required force which I found interesting. Also of obvious note is that the keys int he centre appear to be closer to 50g than the spec'ed 45g.
I shall send the keyboard to dirge hopefully next week - looking forward to hearing your opinions
