I can tell, that Randy Oliver is not good in that issue. Not good idea to follow his opinions. Another area, where Randy is not good, is varroa treatment.
Randy critisize deGroot's results, what he published in year 1954.
He says:" deGroot never implied that a formula should be 1.00% trypotophan–rather, divide all other amino acid weights (or percentages) by the weight/percentage of tryptophan,".
Randy does not know that tryptofan is very difficult to measure from pollens, but it is there. And there is no lack of tryptofan in bees food.
Randy want to find "optimum" percentage to amino acis. But there is no such and that is why bees forage many flower pollen to get enough each amino acid.
USA made first comparative laboratory tests about different pollen recipes 1977. It is almost 40 years ago. Later Australia has made very good work in this issue.
Clearly USA has made much research about the issue but results are company and recipe secrets.

Pollen amino acid content is very expencive to measure. That is why results are difficult find.
