Hi Thomas

I hope it’s not too late but I got into some backlog with reading the list.

For your example I would recommend:
#+TBLFM: @4$1=vsum(@address@hidden); f-2
or if you really want 40 digits precision for the calculations behind:
#+TBLFM: @4$1=vsum(@address@hidden); p40 f-2
Please read my explanations here:

The integer calculation you suggested with decimal point notation is
not possible out of the box and if at all I would rather go the way of
Calc Fractions to get infinite precision:
| 3:10 |
| 3:10 |
| 3:10 |
| 9:10 |
#+TBLFM: @4$1=vsum(@address@hidden); F
