Instead of the last two posts you just offered why don't you explain why testing an OGE hover is better and safer than maintaining LTE at Vy and looking for a given margin?
You still aren't listening.
You pull to your max power BEFORE you get anywhere near the OGE hover ie at the same speed you would be assessing your inaccurate Vy MAP somewhere between 6 and 8 inch power margin.
Instead of relying on an approximate assessment of power available, you have proved that what your charts require and what you have planned is in fact available in the conditions of the day - all while flying quite safely above ETL.
Your way isn't backed up by any empirical evidence or accurate power assessment - my way confirms the POH figures, provided by Robinson, are available - which do you think is more accurate and therefore safer?
Discourse on this website has been a valuable adjunct to that training, but you don't do much to make the process at all pleasant.
Right back at you with that one.
Just understand that the Robinson training system is not the be all and end all of helicopter training - it does what it was designed for, getting people into Robinson helicopters. Plenty of people on this forum have been trained to far higher standards in many disciplines.
