Today (Sunday) at 8:30. SkyPriority had no waiting line in front of it, regular check in was quite busy (no line outside though). Wait in SP area ~5 min. From SP to security check there was a lady checking eligibility for SP, I luckiliy got to skip some people because the Privium gate was free. Going up, yes, regular priority and Privium were mixed. Wait was ~15 min. There was a Privium passenger who "thought" the line didn't apply to him (I.e. he just went under the fence) and he just went to the front. Security didn't see it but a couple of minutes later when another passenger "snitched" and security just took him out of line to the back. So they’re pretty strict.
Alltogether I think from getting out of the car until the lounge, it took me 30 mins
