Im bumping this.
To put this problem in simple terms it means the Games TDC is providing a 17% Ranging error on all firing solutions.
I hope the magnitude of this problem has not been lost in the we need a working chronometer white noise.
In my example above the TDC has clearly provided a range solution of 1,406M while the sub the TDC is sitting in is STATIONARY and approx 1,680M from the target.
