Reports is still badly broken. I get very inconsistent results when using reports. For example, when I choose Group by Year and Cycling I only see the following:
Time Period Count
2010 1
2008 6
No activities showing for 2009 even though there should be many activies for Road Cycling, Mountain Cycling and Recumbent Cycling.
But when I choose one of the sub categories such as recumbent cycling
2010 28
2009 147
There are too many other errors in the reports to list all of the examples but as a reference when choosing Summary and All Days for Cycling I have a total of 413 activities which should be broken down to:
2010 31
2009 241
2008 141
Other selection combinations produce quite a number of other errors rendering the reports functionality total untrustworthy.
