Thanks, that is interesting.
I contacted the crankset manufacturer directly that handed me a document where it states "left arm (shim) 12 to 15Nm", I suspected it was for hollow BB and not square for the mention of left arm only and much lower torque compared to what I came across from Parktool or other sources (which seem similar to what you posted, around 35 Nm), but when I raised the interrogation on is it really 12 to 15 Nm, manufacturer did not answer back.
35 Nm seem to be a value that is recommended on several places so I guess this will have to do...!
thank you for the help
