As you may already know, there are multiple statistic charts in the game. Depending on the chart, we look back a set time of days (ie, 30,90 days etc).
Are you interested in particular in extending the time we keep the chart for any specific one? For example, instead of keeping the total resource crates produced for 30 days, we could extend this to a year, etc.
Additionally, we could create more charts which you can suggest.
Adding your reasoning as why you think your idea is important is required.
Ideally, I may design a new system for these charts, to make such extensions possible. A system that would allow easier record keeping for much longer time (ie, years). However, I am unsure if this is important to you at all and hence why am I asking.
Do note that priorities will naturally be affected by your feedback but this is not something that will happen right away. Still, if important feedback is raised, due to the nature of the request (every day we delay this, is a lost day in terms of statistics), this may change.
