perhaps you could use the condition of the water beneath you and relate it to the Beaufort scale.
Most helos produce something that would equate to a Moderate sea state - that is equivalent to a Force 5 or 19 - 24 Kts
To get to 50 Kts you are talking Storm Force 10 which would give Sea state 8 - if you have ever been out in those conditions at sea, you will know that is not what exists under a hovering helicopter.
Well it was 50kts the day I did it with the handheld wind meter and yes I have spent a lot of time at sea and if you enlarge that wind to make it comparable to the size of the sea it would be force 10.
Lots of ifs and scenarios in your posts crab but if you don't know something it's ok, no single person knows everything and it's ok to say I don't know especially if you actually don't.
Or just say nothing or in this case post nothing rather than say what someone else has actually done is wrong or lies or whatever you meant.
