Hi all
Thanks for comment.
At the time I needed it there were only 4Ah batteries in stock, and I
got what I got.

For light tools 4Ah is fine and I now have two.
If I do lot-lot-lot of bigger drilling, might stock-up on higher Ah
batteries.  Come that time there could be some "new" battery I am glad
it is my option to get.

Comment / reminder - I got the biggest drill using "small tool" batteries.

 To be fair... My experience is that you still get useful power out of
the "moderately" large batteries like your 4AH as opposed to 5AH.  It
just may not be "as powerful."  Where you see huge differences in base
power even over a very very short time is the smaller batteries.  Often
the "cheap" batteries packaged with an all in one kit.
Tool/battery/charger...  They don't give you full power for a short
time.  They just don't give you full power at all.

If you could access the electrical circuit a PZEM-051 meter would give you all the useful data. For under $20 they measure DC up to 100V and 100A, calculate the power and the total energy in Watt-hours.
 

Torque Test Channel does some decent testing using a load.  I don't need to be an expert on the details.  I just need to know the results, and remember my anecdotal, but not irrelevant, direct experience.
