I went back and referenced this thread:

It would be interesting to have had the chart also cover if the respondent was using a compressor fridge and what the fridge cf capacity was. But a good number of the replies also stated type of fridge and some the capacity in the text of their response.
It was interesting for me to reread the thread with my current eyes.
cheers
