What's Your Real 78?

The number on the card is not the number you shot.

You shot 78 yesterday. The card says 78. Your buddy who shot 76 at his cushy home course in 4 mph wind thinks he beat you.

Did he? Genuinely — did he?

You played a 7,100-yard track at 1,200 feet of elevation in an 18 mph crosswind, 54°F, on greens that had been cut tight for the club championship. He played his neighborhood par-71 in a t-shirt with cart paths only because of overnight rain.

You both shot in the 70s. That's where the comparison ends. Until now.

The BASED™ Calculator

We built a free, public calculator that does the math the rest of the sport refuses to do. You give it:

• Your raw score
• The course
• The wind, temp, and altitude that day
• The date

It runs your round through the same five-layer ECN engine that powers every SwingBase league and every SwingBase tournament:

1. WIA — Weather Impact Adjustment
2. AA — Altitude Adjustment
3. SCI — Seasonal Course Index
4. CVF — Course Volatility Factor
5. PPD — Player Performance Distribution

And it spits out your real number. Not a handicap. Not a guess. The actual translation of your round into "what this would have scored on a neutral day."

Your 78 might be a 71.2.

His 76 might be a 75.8.

You won. By a lot. The math has receipts.

What to do with your real number

1. Screenshot it. Post it. Tag it #WhatsYourReal78.
2. Send it to the buddy who beat you on paper. Watch him do the math himself.
3. Start a league where everyone plays under BASED™ from day one. (Here.)
4. Run your next tournament on it. (Here.)

It's a new way to see your round: what you shot on a neutral day, conditions and all — a companion to your Handicap Index, not a replacement for it.
