Percentage score calculation with numerical

[tehgringe]

The Datasource file generated sets a percentage score value, and when I create a threat group layer and then attempt to merge the layers, what have others done to go from mixed value types (whole numbers and percentages) so that you can AND then to get the equivalent output in the video.

Datasource TRUE, Attacker technique FALSE
Datasource TRUE, Attacker technique TRUE
Datasource FALSE, Attacker technique TRUE

I took a look at the expressions documents for mathjs, and experimented with Navigator. Am I missing something, and do I need to change the way the scoring is output from DeTTeCT so it is not a percentage value type?
