The formula in question is the culprit in this case (at least as stated
there).

: $2=$2=vmean(@<..@>)

Second column is equal to the second column which is equal to the mean of
all the values in the second column (including the header "Sys").

If you change the table as follows:

| Date             |   Sys | Dia | Pul | Sugar |
|------------------+-------+-----+-----+-------|
| [2014-04-27 Sun] |   125 |  88 |  78 |    92 |
| [2014-04-28 Mon] |   102 |  88 |  86 |    92 |
|------------------+-------+-----+-----+-------|
| Averages:        | 113.5 |  88 |  82 |    92 |
#+TBLFM: @>$2..@>$>=vmean(@I..@II)

All the values will properly compute.  If you want to avoid the second
HLINE above Averages: then change =@II= to =@>>= (penultimate row)
