We have "ages ago" testing it. With laboratory like equipment. Namely, in water cooling PC
(CPU and GPU, best temp metering as you can have).
Considering my language barrier, only as much, this was not good idea. With 30% ratio, temps are replicalbe worse as with 30% Basf Glysantin G40.
Our Nurnberg racers - with ratios of antifreeze between 35% and 40% - vow for Millers ExtraCool. In 1/3 (!) of Millers recommendations. If you exaggregate in ratio of such adds, the "water" inclines to froth (!) and cavitation is not good charactersitic for coolant... .
Fancied is also Lubegard KoolIt. Especially for it color indicator for "fumes" in coolant, as very first and very early sign of even a bit blown head gasket.
I use many stuff from Redline and Iam very pleased therewith. Very. But not with WaterWetter. For me its a bad product.
PS:
Apart of thermal questions, you NEED 10-15% ratio of antifreeze,
to prevent rust. Also pro racing teams using mostly ~12% of antifreeze in water.
