Looks like today was just a late nadir and he came up for PS on his own. Nadirs can be later if they are breaking a bounce.
Do you know how much of a bump in numbers Wesson gets from his food? The "no food" 2 hours before preshot is what we tell new people so we know the PS number is not influenced by food. Once a person knows how much food will bump up the numbers, you can factor that in to decide if it's safe to shoot. For example, if you knew he got 30 points from his meal, and he was in the 80's at PS time, that might otherwise be the 50's without that food.
