If your target audience says too lazy didn't read - I think the bit that applies like a rule of thumb to most cases is more relevant and has a higher practical knowledge value than the intricate details or an "it depends".

(Similar how you can just explain gravity with newton instead of einstein, to make it short, even though it is less precise or technically false)

That was a fascinating discovery. It seems Pascal and Fortran in particular fit into the "faster but less efficient energy-wise" category. I wonder what's going on there.
