The problem is that this picture alone cannot tell you whether the diamond is good or bad. Comparing it to the ideal-scope or firescope images of other stones would tell you whether this diamond has more or less leakage.
Diamonds with severe leakage should be rejected. Diamonds with little leakage should be seen. There is no guarantee you will prefer a diamond with no leakage than the one with small partial leakage.
Diamonds of different proportions can have very little light leakage but they might have different look, different contrast, scintillation, dispersion, etc.
You also have to take accuracy of the measurements into account. +/-0.2 degree of pavilion angle can significantly change the result.
There is nothing in the numbers for this stone telling this stone is bad. DiamCalc simulation shows quite small partial leakage under the table.
Hope this helps
