I've re-tested Tenon on 5 February 2018 with the January 2018 version.
This results in a change to 7 tests and a decrease from 37% to 34% of barriers found. But Tenon still keeps its second place.
Although I've tested with an updated version of Tenon, another update which includes lots of new tests is apparently still coming. I will need to test again when that is out.
