Experiment #157 : Grinder Temperature and Extraction

For awhile now, we've experienced a streak of inconsistent timings with our espresso brewing. Shot timings changed radically every couple of shots after calibration which had our whole team scratching their heads. We've set out to discover the reason behind this mystery.
For awhile now, we've experienced a streak of inconsistent timings with our espresso brewing. Shot timings changed significantly across the day which had our whole team scratching their heads. After reading about The resistance of Heat by Michael Cameron, it seems like his discovery about the grinder's temperature rising and decreasing across the day has a significant impact on the resulting extraction and shot times. We've set out to investigate this mystery with a couple tweaks of our own.

We decided on the test using the same grinder as Michael, the Mythos One Climapro Grinder but this time in two different states. The first will involve the heating elements unplugged with no interference to the grinder burr temperatures. The second state will involve having the built-in heating element plugged in. This means that there will be a heated chamber where beans will reside prior to being ground. The fan elements will also...
