reliability of statistics graphs

On Jan 2, the statistics for my tunnel displays the following: an hour-long transfer (output) at 1.3MB/s at 1.3M Packets/s while showing the loss going up to 100% exactly with the beginning of the transfer. It would suggest that ~4GB of data left my computer on that morning.
My question is: do I have to take the information from the graphs seriously (~1-byte packet payload?) or can I safely ignore it?
Thanks

Welcome to the wonderful world of RRDTool which has counters which wrap and when it incorrectly detects that wrap it guesses that the counter has fully wrapped and thus fills in the missing bits. This causes a huge spike in the graph.
