I can definitely relate, all I can say is when I have these days, my thoughts after are "I can feel a good round coming". It might take a little while to actually come out but its definitely coming. I'm in one of those moments now, you just look back at where you've made the odd stupid mistake or not quite chipped it close enough there or holed enough putts and it impacts your score.
There's loads of times I've hit the ball well and scored poorly, be that putting poorly or just generally not making the most of scoring opportunities. Some days the hole is like a bucket other days you can't buy a putt. It's just golf.
This weekend I shot 74 (+3) with 35 putts. Didn't hit it particularly close to any hole, had a couple of 1 putts, couple of 3 putts. Just a good, but not quite, day.
