In this case it would have been useful for the groups of lights to contribute to the allocation of samples.
It is intentionally not taken in account: if you use light groups, you are going to change their intensities
after the rendering, taking into account their intensities
during the rendering is a wrong idea (because it is going to change).
The optimal setting is using a light intensity for the lights, during the rendering, equals to the average value you are going to use after the rendering.
Otherwise, you may start to have problems with floating point precision (and you can still have) if the intensity ranges are big.
