hi
i have tested the value that it should be .75 and it works ok.
the bet showed on the screen at 43 seconds before the start time.
you have to take your refresh time in to the calculations, because of the trigger queue etc.
so if you have lots of triggers and the refresh rate at 2.00, then it might not fire until 35 to 40 seconds before the start time or whatever waiting time you are setting.
also you could try using the mf_second*45
