Optical monitoring of 50 EGRET/LAT detected Blazars since the launch of FGST provides a one year let of simultaneous GeV and eV lightcurves, sampling the inverse Compton and synchrotron components with unprecedented regularity and coverage. We find a very close match of flares in the two waveband regimes with little evidence for orphan gamma-ray flares. Despite the match in occurance, the amplitude scalings and temporal lages differ within individual sources and within the entire sample. We discuss the effect of binning, and the resulting uncertainties for scaling relations. The results provide clues for the details of inverse Compton models of Blazar emission.
