It looks like you have an awful lot of null in there (6+7+8+6+7+8+11)*2 = 106 sec of stimulation The total run length is 130*2 = 260 sec Leaving 260-106 = 154 sec for null. There are only 7*2=14 events total, so the average null will be 154/14 = 11 sec
I'm surprised that one null was 75 sec, but not too surprised.

Hi, Optseq2 is returning designs where the last NULL even is upwards of 75 seconds (more than 4 times my psdMax!. Can I keep the rest of the order as is, and just truncate the last NULL event to be equal to my PsdMax value? Below is my command and a sample output file:
