I couldn't find very comprehensive statistics anywhere on reasons for termination of tenancy but my guess is that the six-year rule was very seldom used.
I am not sure many landlords were even aware of it. There was very little point in exercising it either as any new rent would be governed by the previous one, and if you want to sell, renovate, or occupy yourself you could do than anyway.
