Rounding errors

I am getting lots of rounding errors. Is this normal? And do I get credited for the CPU time spent when it continues from the last save file?

Your computer is OK. You are testing an exponent very near an FF crossover.

You do not get any extra CPU credit for the time it takes to resume from the previous save file.
