Yes. It’s best ball. You start with four picks. Each hole you have 4 chances for a good score. You get the lowest score of all four on each hole. If all four birdie the lowest score is birdie and you get one. If some eagles you get two. If no one birdies you get zero. If any miss the cut, you go to the final two rounds with what you got and you just have less players providing your chances at birdies. Participant with most strokes under par after Sunday wins and gets called a cheater.
I use pgatour.com to keep up with my scores and I put each of my players into a spread sheet I made along with the course pars and it tabulate everything for me by day and total. I normally only enter my Thursday and Friday scores up until close of business on Friday and don’t really keep up with it over the weekend except for checking thread updates.
If you are really serious, you can view player profiles for the tournament on the PGA website and see what their performance is for hte season by tourney, how many times they've missed a cut, etc. I used to do that a good bit. Not so much now unless I'm branching out to try someone different. I have a couple favs I gravitate towards cause they don't hurt me too often and most of the time of late they give me a decent result. Rahm has hurt me the last couple times I picked him. And then you have certain players whose game favors certain courses. You wouldn't necessarily pick Rory on a tight heavily tree lined course. He's a Links player by default. And he just seems a little off this year. Just some different ideas how to go about it based on the fun/competitive balance you are participating with.
As far as how 95 keeps up, not sure. I could expand my spread sheet and do it with how I set it up, but I would have alot of repetitive score entries. If I were doing what he does, and if there's a site I could dump the field into an Excel table each day, I'd set up all the participants picks, export the scores, and let a lookup table sort everything out in mere miliseconds. Props to him for doing this for us. I took care of the Canadian Open field selections for him while he's on Vacay and it does take a little time doing it the way I did. Could be a quicker way, and definitely is a much longer way. 95 definitely invests some personal time in our entertainment.
