Mine actually starts below one with the blade installed. Something sounds off with yours. I hope the thread isn't stripped on it or something.
I love my Variant and it's my daily driver. I can do things with it you just can't do with a non-adjustable razor. For instance I can do an ATG pass set just below 1 and it doesn't cause any irritation. Quite often as my blade gets duller I'll do a first pass on 4 and shift it down to 3.5 on the last two passes. One week I was suffering with some "One Shave Too Many Syndrome" by being too lazy to change my blade, so I shifted it down to 3 all week to recover. It still gave me a great shave and allowed the recovery. I've never had mine above 4 though.
