Hi Farber,
I had a problem with duplicating the "post patch speed" for the Mk1a on the B6 posted graph in your post above. I am presuming the graph is in TAS.
Graph says post patch CloD Spit I should do a top speed of 570 kmh TAS at 6200m (FTH), 540kmh TAS at 5000m.
I got a lower FTH of ~5000m vs graph 6200m (boost declines above), with 520kmh TAS at ~5000m (***). So (-20kmh TAS) at 5000m, and (-50kmh TAS) max speed. I had to reduce rpm to 2750 (full rad) otherwise I couldn't do speed runs at FTH without blowing the oil gasket, quick bursts of 3000rpm did not suggest accelleration (before near instant engine fail) though.
Would be happy to revise these in light of other's data (in case of error or my install somehow giving different results) but imo the patch FM does not match the B6 plot (at least according to the Spit guages). IAS to TAS conversion is by an approx rule (2% increase per 1000ft), a more accurate calc is not possible without knowing more about the CloD atmospheric characteristics.

*** original SpitIa patch +hotfix data 245mph IAS@16500ft if anyone wishes to check.
