And I thought we were talking about an S61 full of pax not a 412 Trog - I suspect the SE HV curve is a good deal bigger than the 412s.
Your defence is that you don't do it because you don't practice it - my answer is then go and practice it. You shouldn't be flying pax around if you can't do autos.
An ex BA 747 training captain told me that senior pilots were having to hire light twins to keep their flying skills going - their sim training was more systems failure and management thereof and they never got to fly the real aircraft because they were always full of pax. Their pure flying skills eroded in the same way you are bemoaning yours going, simply because no-one mandates you do GH every month (not profitable). Do you really think that is safe or sensible?
Many people believe that what can be done in the sim will work in real life, especially with TR failures, without understanding that the sim (any sim) isn't modelled accurately for TR malfunctions - you need the data from the real aircraft in the real configuration for that, not a best guess from interpolated data.
You carry on convincing yourself that you know better than evryone else but you'll find that 40 kts isn't sufficient to keep the nose straight with no TR and you can't expect the pitot-static system to measure it accurately anyway, especially with the high levels of sideslip involved.
