So now you're being ingratiating: Establish common ground by
divorcing yourself temporarily from your ultimate goal and lose the
battle in order to win the war.
What you neglected to mention was that prior to the initialization
of the software phase of the project the hardware issues needed to
have been worked out.

Caca. You presume to know enough, up front, to determine how a test
should be set up, and run, to yield a minimum cost or a best
OK, here's a challenge for you: I've got a platinum resistance
thermometer with an R0 of 100 ohms.
Outline the experiments you think I'll need to run which will allow
me to realize the least cost method I can use to get to 1% error
from -50°C to 50°C with a totally analog system over an ambient
temperature range of -55 to 105°C.
Include the cost of your system and justify why you think it's the
cheapest way I could do it for the accuracy required.
