This graph (posted in this thread http://forum.1cpublishing.eu/showthr...=34115&page=10) showing top speed at altitudes ranging from sea level to 35 thousand feet seems to show the Spit having a slight edge on the 109 at altitude:

Your chart is for an E3, and secondly, it does not specify boost level for the engine. I do not think it is for an E3 using the potential boost allowable during BoB.
It is also more importantly not an actual German test document, but a chart derived from a couple of secondary sources.
And the Spitfire performance is noted as being 'slightly adjusted' by Alfred Price, based on a couple of assumptions which may or may not be accurate.
I would recommend you study the actual test charts available on this site:
