Hi Axel,

The information shown as used is a bit misleading.

After the buffer has rolled over, it is always 100% full.  The 
utilization shown is the point in the buffer that is being written 
to.  So anything in the first 24.2 % is new, anything in the rest of 
the buffer is still there (and readable) from the previous cycle.

Cheers,
Kev
