Woah - easy there tiger.
I would guess that 99 percent of the time, full to the brim caps are mass produced, whilst your 1/4 full ones are not. I don't think this is an absolute because the human nature is not absolute.
I would guess that 99.9 percent of the time that mass produced caps are not 1/4 full. (follow the logic, its there).
I can remember a European ecstacy manufacturer being quoted as saying that caps are always packed full if they are mass produced. (source: The Book of E).
There would be some troubles for your Jo Eastern Suburbs in making full caps. You would have to get the ratio to filler right for a start. I think most gel caps are 500mg, but is that 500mg light fluff powder or jam packed tight stuff? Then the packing of both ends of the cap before putting them together with the powder in the sealing sections making it difficult.
The extra work and effort involved in stuffing caps full for no real reward is going be appealing for our Jo E.S. when he can just through 100mg in, cap it, and be done with it.
If you are going to be so childi... err critical, at least be constructive and add something useful to the thread.
Cheers,
Soma.
