There isn't really any hard and fast rule, it depends on what the cap is used in.
For what it's worth, I bought a bunch of new electrolytics not too long ago and measured them with my DIY meter. None showed more than 5Ω of ESR. Some of the old ones I was replacing were as high as 40Ω. These are lower values than shown in that table, but of course that device probably uses a different set of conditions.
