40-50nm
Isn’t hat equal to torquing with 40-50 kg and a 1 m wrench? To my knowledge you shouldn’t grease the crank bb interface to prevent the crank arm slide too far onto the spindle. Making me think 50 Nm could be too much.
Anyway, a 10 cm Allen key gave me another quarter of rotation on the screw, hope that will help!

you could argue that grease will help the crank sit on the spindle properly, preventing movement and damage later on. Also prevents corrosion between the aluminium / steel axle.

No, it's more like 4-5kg. The weight of a 1kg mass on earth at sea level is 9.8N, give or take a bit depending on where on earth.

Your knowledge is wrong. It will take less torque to get the crank in the right position on the taper if all the sliding contacts (taper, thread, under the bolt head) are lubricated.

Right, well that's probably by far not tight enough to start with. Sugino suggest 40-50nm which is a lot tighter than you'll be able to get with a mini tool. Riding it loose may have ruined the taper now though.
