Glare - CIE 112 (GR:36) vs. 12464-2 (GR: above 90)

Hi guys

I have a project where i calculate the GR in 1,6 meters. According to the EN12464-2 my glare rating is above 90. When I switch to the CIE 112 method my glare rating is 36.

It seems like a big difference and is it okay to use the CIE112 method when i am using the values in EN12464-2?

How is this possible and is the GR acceptable to be used in a project?
