When making crafting profiles you have all the skill details when you choose a skill. I have understood most of the options... but i am just trying to figure out what these two do exactly

ToT>=
ToT<

I presume ToT is for tricks of the trade, but what does it do exactly...

I am hoping its a counter for how often ToT has been used... but i am not sure.

I have tried to find something on the forums and in the tutorials and have not seen anything. I could have over looked something or am just blind. Thanks for any info on this.
