But Daniel predicted that the rate of success would continue to climb as the kickers grew more familiar with the distance.

“These guys are professionals,” he said. “As soon as you tell them it is the 32, they will practice it over and over. I predicted the numbers would be over 90 percent. It’s a small sample size, but so far, I have been wrong.”

Bede, who is 9 for 12 on extra points, said he spent considerably more time practicing extra points than in years past. At 6 feet 4, 225 pounds, he is an example of the strong-legged kickers who are now more desirable in the C.F.L. The Alouettes released Sean Whyte, one of the most reliable kickers in the league, in favor of Bede because of Bede’s strong leg.

Under the new rules in both leagues, if an extra point is deflected and caught within the end zone, it can be returned by the defense to the opposite end zone for 2 points. Therefore, teams need the kicker to launch the ball out of the end zone, particularly in the C.F.L., where goal posts are on the goal line and end zones are 20 yards deep.

“Everybody’s going to stronger-legged kickers,” said Higgins, the Alouettes’ coach.

Higgins, Daniel and Bede all said that the kickers in the N.F.L. were generally superior to their C.F.L. colleagues, and in the first 13 N.F.L. exhibition games, only one extra-point attempt was missed.

Daniel was also involved in deciding the new spot of the 2-point conversion. He calculated the percentages of plays from each yard line inside the 5 and found that teams scored touchdowns on 90 percent of plays from the 1-yard line. Plays from the 2-yard line were a little less successful, and plays from the 3-yard line were successful 50 percent of the time.

According to Daniel, the data on 2-point conversions has been remarkable. Of the 141 applicable touchdowns, teams have elected to go for 2 points 32 times, a rate of 22.7 percent.
