What exactly are you trying to find out by taking these readings?

If you want to know how much power is being used (and do not care about power factor) you take each reading and multiply it by 120, then add. Or add first and then multiply by 120. Or you can take the average and multiply by 240. In all cases the answer will be the same.
If you want to know if you are overloading the panel, you look at each leg separately.
A 200A panel can safely handle 200A (non-continuous) on each leg. You do not add or average for this purpose.

Code wise that is not an acceptable means.
That is why I was asking what the purpose of these measurements where.

Yet still I will ask for what purpose.
If it is for just curiosity's sake than sure just put the clamp around each and there you go.
On the other hand if you are trying to determine if you have capacity to add more load and are under the NEC you need to follow the routes found in 220.87
