bug IR drift vs Flight time 1.03

[Hélène CIZERO]

Hello, after a 10 hours flight, it is impossible to get 0 GS displayed on the NDs. There should be a residual 2-3 Kts because of the IRS drift. So I investigated further and checked the DATA / POSITION MONITOR page and it shows 0.1 NM error for the 3 IRSs which is also totaly impossible after 10 hours of flight. Could you add some drift to the IRSs to reflect more reality ? Below is a table of the acceptable drifts vs flight time.
