I have to hand it to them for being candid in their PAQ (Previously Asked Questions) and apparently telling the base oils used, not blend ratios mind you but at least telling that Group I is used for the Comp 4 range, Group III for the Pro 4 Range, and Group IV PAO for the Pro 4 Plus range. Note from the below that Esters are apparently used as a blend stock in each product with the variant being the base oil Group type (I, III, and IV).

About half way down the page:
..."True synthetics are Poly Alpha Olefins and Esters. Our Pro 4 Plus oils are blends of these."
and
"...The Comp 4 range is a blend of esters and mineral (Group 1) oils with good quality additives. The Pro 4 range is a blend of esters, MC (Molecularly Converted - Group 3) oils and top quality additives. MC base oils are considered to be synthetics. These oils have similar characteristics to PAO's (Poly Alpha Olefins) which ARE True synthetics."
and finally regarding the flagship Pro 4 Plus lineup:
"...Pro-4+ is a true 100% ester/PAO synthetic with the most shear stable VI improver polymer available on the planet. (This type of 'true' shear stable synthetic is very rare. We only have 2 or 3 competitors.)"
