S76A Transient Limits

Simply---Does pulling up to 115% (230% total) torque for under 5 seconds exceed RFM limits?
Long version---In the limitations section of the RFM, reference is given to figure 1-5 which states “Transient – Time: 5 Second – Transmission Torque Limit: 115%”. This is not an OEI limit. One could interpret this as a 230% total torque limit. FlightSafety seems to agree with this interpretation.
Right after the RFM reference to figure 1-5 is “NOTE: …the sum of the individual torque values does not exceed 200%” there is no other reference to the 5 second limit.
Which is it?
Also, there is not an "Intentional use of transients prohibited" clause. What is Sikorskys position on this?
