So I filled out the whole survey, and then I got to the part about the digit ratio, and I thought, OK, I'll do this! But I can't do it now (no photocopier at home, can't trust a measurement to 3 digits if I'm not doing it the same way as others). And I can't keep my answers up until I can do it (no battery in computer, must be turned off to transport, Lazarus plug-in has been problematic). So I put in a public and private key but no data. I will gladly supply the data to you tomorrow, using those keys to identify my survey.
