Is Capping/Betting head-to-head matchups (rounds) really that difficult?

I just went through some daily figures and I've now lost 6 in a row and about to lose another. I put work in looking around, past tournaments, how they are playing now and of course how they play at a particular course. I also factor in a bad round, bouncing back for a player and other small stuff like do they play better in the afternoon....
But it doesn't matter. And of course today I decided to go oppo just to see and my dude is +2 through six. Plenty of golf left but still crazy.

Any tips are welcome

think on daily matchups have to go with the golfer that shot best the previous round esp on the back nine. looks like it is a "momentum" thing.

BUT then you have the Dustin Johnson's of the world that are "a box of chocolates" one round to the next
