[tor-commits] [onionoo/master] Fix comparison in writing uptime documents.



commit 203d5d885d4155ed719c5168430ba237bad734aa
Author: Karsten Loesing <karsten.loesing@xxxxxxx>

    Fix comparison in writing uptime documents.
    
    In the spec we write: "Contained graph history objects may contain
    null values if less than 20% of network statuses have been processed
    for a given time period."
    
    However, in the code we checked less than or equal. We should fix
    that.
