I have made the changes and did some testing, but there are no "00 00
01" series in the data at all. Some strange patterns I can see, but
mostly just garbage. I will try again this evening when I can be sure
that there is a program running.
Fortunately I remembered wrong the end date of my subscription, it is
valid until the end of this month, so I have 24 hours more to test this...
