Good day everyone,
So yesterday a discrepancy came up between the stats displayed for the Swedish premium TD, the Strv S1. Anton Pankov had previously announced that this was likely a display error, and an official statement from WG states that that is indeed the case.
In short (and paraphrased somewhat), third-party services are “catching up” with the server based tank statistics, which are more precise than those shown on third-party sites and the actual game client. WG is working on code to help prevent such discrepancies in the future.
