What was the use of pedal during that method?
Ever just stick a boot full of up hill peal and see how the aircraft responded?
I found the nose pitched up....which prompted a forward movement of the cyclic and as the aircraft was not descending at a high rate the demand for collective was reduced which assisted in he recovery.
Next time you fly that Lynx....give it a try and see what happens.
With a constant Collective setting and bank at the input of pedal...see if what I describe happens.
