In GENERAL - either get 5 strong reps at 95% or make sure you can do your TM for 5 reps.
Just a general rule that seems to work for just about everyone, regardless of template. Over the long haul, training is linear. When you take a microscope to it, there are peaks and valleys. I don’t know and will never know why people think strength training is always, and at all times, linear.
That is why you use indicators and use the right tool (in this case, the TM) for the right job.
