I'm wondering whether this PR can help to enable any disabled activation tests or not?

I'm wondering whether this PR can help to enable any disabled activation tests or not?

this PR doesn't enable activation tests, I think these tests rather depends on number of segments for PWL, probably we need to use configuration option PWL_ME or change the plugin behavior to chose the biggest possible number of segments without this option,
also more accurate calculation of scale factors for activations is provided with using POT, so probably pre-processing of GNA tests with POT can also help to enable these tests
