Hi. I’m not sure why you are worried? That’s not low. Meter variance is 20% so those numbers are the same. With SLGS you shoot 200 and over when new and work your way down to 150. You don’t have any mid cycle pm tests.Many cats drop lower at night than during the day so you just have half if the picture. It’s a good idea to get a +2 and if lower than the preshot set an alarm to get a test around +5-7.
