Waiting times at Ukrainian land borders

I am soon travelling to Ukraine by car and will be entering from Slovakia or Hungary. I have read many stories about the notoriously long waiting times at the Ukrainian land borders. Waiting times of several hours are allegedly nothing unusual.

I know that Ukrainian Customs operate a website, which lists current waiting times at all border crossings, e.g. for entry from Slovakia or Hungary. Do anyone have any experience regarding the reliability of this information? Just while writing this question, the estimated waiting time at the border crossing from Ubl'a to Malyi Bereznyi changed from 5 hours to 1 minute.

I had also expected that trip planners, which in general take account for current traffic when calculating travel times, also considered waiting times at the border, but that does not seem to work for at least Google Maps, HERE WeGo or Bing Maps. According to the Ukrainian Customs website, the waiting time at the border crossing from Beregsurány to Luzhanka is currently about 1:30h. All of the three mentioned trip planners indicate heavy traffic at the border, but estimate the trip between the two villages to take less than 10 minutes.

Since I am going by car, I would rather put up with a detour via a different border crossing, if it can save me a lot of time at the border. The most convenient options would be to cross either from Záhony to Chop or from Vyšné Nemecké to Uzhorod and the posted waiting times for these crossings are rarely more than 15 minutes. If someone has any experience from there, they can perhaps confirm if that is realistic?
