I have just bought a Mk1 and found that the trigger is loose on its pin to a degree that the gun would not cock reliably. I have fixed it by incorporating a further spring between the front of the sear and the trigger block. This causes the sear to move under the catch much more positively. The real cure would be to restore the fit of the components, but I am convinced that even with an 'as new' trigger, this mod would give a more positive action.
A mk1 in good nick is likely to put out around 9.5 to 10.5 ft/lb. From what I have read and understand there is not much point in trying for more.
I agree that 10.5 is about optimum.
My Mk1 .22 was fitted with a "power" spring before I got it and puts out 11.6 with Original Eley Wasps but it is not exactly easly to cock or smooth on recoil
I am about to overhaul it and fit an original spring and at the same time I will do the Chambers nylon+O-ring piston seal conversion.

Opportunity is missed by most people, because it is dressed in overalls and looks like work.
