Dear MHC team, In the [Nature paper](https://www.nature.com/articles/s41597-019-0016-7), you wrote: ?_For the current data release, participants were allowed to enter survey responses that may not be physiologically possible_?, which ranges did you use to correct for unrealistic values? Next, you wrote: ?_6,870 completed all surveys presented in the first 8 days of their participation_? How was this ('all surveys') defined exactly? When I try to link all unique _healthCodes_(I decided on ranges for more or less physiologically possible entries myself for now) in each survey/data-file (including the 6 MWT files), I only find 308 unique users. If I exclude the 6MWT files, I find 1,072 unique users. I do not yet understand why the difference between our findings is so large. Would you have any explanation (except for the fact that there might be, despite checking thoroughly, a mistake in the code)? Thank you very much in advance!
