Gives:

Funnel Beaker a) 4200 — d) 2650
Corded Ware b) 3000 — e) 2350
Bell Beaker c) 2900 — f) 1800

To recalibrate the dates Biblically within this framework:

The following comes close enough to my mind, I have avoided to get as far away as fifty years from the target:

A) (2041+2019)/2=2030 (76.6964+77.8962)/2=77.2963 2150 + 2030 = 4180		D) (1700+1678+1678)/3=1685 (87.575+89.4653+89.4653)/3=88.8352 980 + 1685 = 2665
B) 1778 85.976 1250 + 1778 = 3028		E) (1655+1633)/2=1644 (91.4498+93.3283)/2=92.38905 650 + 1644 = 2294
C) (1756+1734+1734+1734)/4=1739.5 (86.4346+86.8913+86.8913+86.8913)/4=86.777125 1150 + 1739.5 = 2889.5		F) (1588+1566)/2=1555 (97.068+97.441)/2=97.2545 230 + 1555 = 1785

Apart from reducing an important part of European pre-history from 4200 BC to 1800 BC to the lesser span of 2030 BC to 1740 BC, 2400 years reduced to 290 years, 8 times less extended, I have also shown how my tables work, since part of what is not shown is explicitated in these calculations. Line 1 of each is the Biblical year. Line 2 of each is the carbon level back then (and not the one remaining right now), Line three is a sum, first the extra years resulting from the carbon level being back then lower than 100 pmC, then the real year, which added together give the carbon dated year.

Let's check. This time we'll do a date involving the age up to now and the remaining carbon now. We'll take the oldest.

2030+2024 = 4054
61.238*77.2963/100=47.334708194
6200 old - 2024 AD = 4176 BC

So, the apparent age is close enough to what it's supposed to be./HGL
