These judges really are the wurst.

Perennial Nathan’s 4th of July Hot Dog Eating champ Joey “Jaws” Chestnut devoured the competition — and his own world record — Wednesday as he downed 74 hot dogs.

But viewers of the annual Coney Island chow-down were left scratching their heads, as the official tally had Chestnut downing just 64 franks.

The legendary event’s judges turned out to be complete weenies when it came to basic math, as they lost count of how many dogs Chestnut and runner-up, Carmen Cincotti, had eaten.

“I knew early on that they messed up. I can see the counter in front of me,” Chestnut told The Post. “At the first minute, they had me down at 10. I knew it was 20. They fell behind really quick.”

Officials eventually boosted Chestnut’s total from 64 to a record 74. Cincotti’s tally rose from the anemic 45 displayed on the broadcast screens to an official 64.

The results were even officiated by Brooklyn DA Eric Gonzalez, who happened to be on hand.

The dog debacle didn’t throw Chestnut off pace — the California native was keeping track of his miracle of mastication in his head.

“I didn’t let it bother me If I let it bother me, I’d slow down and not win the contest,” he said. “I know there is a system. I know they double check. At the end, I knew I’m at 74 — 64 feels a lot different in the stomach than 74.”

But Cincotti, who celebrated his birthday with his third hot dog eating contest Wednesday,i said he was thrown off his game and called the contest a “clusterf–k.”

“I was completely aware the numbers were off. I had no idea what number I was at,” he said. “It’s like running a race blindfolded.”

He added, “I was trying to be safe, more so just because I didn’t know where I was and didn’t want to push harder than I had to if I wasn’t even close to Joey and completely lose it. If it were close, I would’ve definitely pushed a little harder.”

Cincotti called the botched judging a “clusterf—k” and says it takes away from competitive eating as a sport.

“It’s embarrassing for Nathan’s and for the Major League Eating organization,” he said.

Major League Eating, which sanctions the contest, said it’s reviewing the judging process and plans to issue a new set of protocols for next year’s competition.

Meanwhile, Miki Sudo smashed 37 franks and buns down her gullet to notch her fifth consecutive Mustard Belt in the women’s competition. Michelle Lesco came in second, scarfing down 28, and Juliet Lee placed third with 25.

Sudo and Chestnut earned a cool $10,000 apiece for their gluttonous feats.

The 216 1/2-pound Chestnut makes a living as a competitive eater and holds records in categories including apple pie, gyoza and tamales. But ahead of competitions, he maintains a healthy routine that includes yoga and running.

“This year I did 10 practice runs. It’s a battle. I have to eat healthy and I recover. I run and I lift weights,” he explained.

On Wednesday morning, he guzzled a gallon of water to prepare for Nathan’s — where he bested 20 other competitors amid scorching temperatures and stifling humidity that made it feel like it was in the upper 90s.

“I woke up at 4:30. I had a cup of coffee,” Chestnut said. “I stretched, did my yoga poses and stretched some more.”

After consuming more than 20,000 calories in one sitting, food is off the table for the rest of the day.

“I’ll be looking to take a shower and drink water and take a nap,” he said.
