engine mount bolt torque (Ecotec)

Question

('07 Cobalt LS, 2.2 L)

Re the passenger side engine mounts, ...
The Alldata manual (AIUI, from Helm) says

Tighten the engine mount to body nuts to 66 N.m (49 lb ft).
Tighten the engine mount to bracket bolts to 130 N.m (96 lb ft) plus
45 degrees

But, specs posted elsewhere, credibly said to be from GM Global Connect say ...

Engine Mount to Mid-Rail Nuts 100 N.m
Engine Mount to Intermediate Bracket Bolts 50 N.m

These seem seriously different, esp 50 Nm vs "130 Nm + 45 degrees".

Does anyone know? Has anyone done "130 Nm + 45 degrees"?  It seems like a lot.

Edit: (Not an answer)  I torqued the bolts to 50 Nm, with thread locker.  So far, doesn't seem to be a problem.

5 degrees seems much too small.. Perhaps it is a typo...

But 45 degrees is more likely, and seen 90 and 120 degrees for some bolts - depends on the design of the bolt and the "stretch" to be accounted for.
