Razer Synapse MS question for macro

so had a question and i looked but i didnt see any definity answer on this.
say i wanted to have a 250ms the way the macros in synapse are they have 2 sections
1 is on the actual recording aspect of the macro where its looks like
0.125 (down arrow)
0,125 (up arrow)

then over to the right side it says total duration .5

can some one explain how to set mine up so its running at 250 MS what i would put in for the times on both the record side and total duration side
