I have posted a piece here which is also on the TT topic, but is more general and I think a new thread would be better. Your voice is heard. See below.
The ESF report commissioned to test meter tail connections is useful, but in my view flawed. It did find difficulties with tails connections in many designs of main switch or RCD, but really made no useful recommendations or conclusions except that connection followed by tails movement was, in general, bad and led to a movement, disconnection under tension or lack of tightness in the screw.
