The statistics page will go "on vacation" again up to Sunday 29th. While there won't be updates to the page during this period (except maybe on Monday/Tuesday 23/24) rest assured that all valid games played will be counted when the page is updated again on Monday 30th.

Note also that:
On Monday 23rd it will be August 1918 so you'll be able to use the Siemens-Schuckert D.IV.

On Monday 30th it will be September 1918 so you'll be able to use the Sopwith Snipe.
