You might be confusing the definitions of eutetic point and freezing point. Not many people call it the eutetic point as it is commonly referred to as the freezing point.
Each mixture of ethylene glycol and water would have different points. A 50% /50% would have a -34 F freezing point and that would be the eutetic point of that mixture but a 60% ethylene glycol
Freezes at -49 F and a 70%
Freezes at around -60 F or so. It is difficult to measure the freezing point at 70% as it gets slushy.
So your estimate of -32F is close but only for the 50% mix. You can get a lower eutetic (freezing point) if you add more ethylene glycol up to about 70%. Over that and the freezing point goes up.
