Thank you very much for your constructive criticism on my writing. I appreciate the candid feedback.

I must take one small issue though. Every engineering project I've worked on has very definitely specified a tolerance. Something may be X cm ± Y mm.

Tolerance is essential to engineering.

As pointed out my comment was not as constructive as it could have been, apologies for that.

It was a bad morning. I do appreciate being called on it.

However my less dramatic point, that precice protocols and exact requirements is what makes technical projects successful, is what I could have conveyed.
