DZR-corrected acceleration times

Hi zusammen

I've found an approach to at least tendentially convert the catalog processing times to realistic times.
Indirectly, transit times are also specified in the 3rd. Specified as the difference between the 0-80 and the 0-100 time.

In the AFN Golf 3, for example, this is 3.5 seconds.
According to the Through-Rate Calculator, the car needs to be in 3rd gear. Gang (which must also be driven in the final part of the 0 - 100 km/h sprint) for this exercise should be approximately 2.9 seconds - at an exact power of 81 kW.

If you subtract the 3.5 seconds from the value in the catalog, you get an approximate "reality correction factor" of 2.9 : 3.5 seconds = 0.83.
If this factor is applied to the entire 0 - 100 catalog time, then instead of 10.8, approximately 8.95 seconds should be shown - for the lightest version, i.e. the "naked car".

It's a nice thought that the 110 would have the power to accelerate from 0 to 100 in about 9 seconds, well below the impressive limit of 10 seconds *gg*
From the often-present factory-installed extra horsepower, not to mention...

My total time of 10.1 seconds, which was stopped in the 2001 ALH Ibiza in the addition process instead of 12.1 seconds (according to the catalog), also indicates a reality correction factor of 0.83 - 0.84.

I'm just wondering why VAG seems to provide such disadvantageous timing calculations for the TDIs.
Approximately 2 seconds for unfavorable circumstances such as a turbo hole, losses during the cavalier start, and 2 gear changes are, in my opinion, quite high.
