Clamping force for carbon saddle rails (Selle Italia Elite Boost)

Hi all,

Long time lurker first time poster, amazing sub!

I've got a Flite Boost Kit Carbonio Superflow MVDP and want to install it on a new seat post. The post has a single (large) bolt which says 16 – 18 Nm. This seems very high, but it's only one bolt and significantly larger so might be ok vs. the typical 2 smaller bolts at ~7Nm.

Does anyone have the manual for the saddle and would be willing to share the section on clamping force? I contacted Selle Italia but guess they are closed until after the new year.

Alternatively, what clamping force would you expect to be ok for the rails? (saddle & similar seat post linked below)

Thank you!
