You do know that you should add at least 0.1 sec to hand times pro day 40s, if you want to estimate what his laser timed (combine) 40 would have been, right. So, the time is closer to 4.58, which is what he looks like on firm. You fell for his and his agent's plan.
Are pro days hand-timed, and how else do they differ from the NFL Combine? Here's more information on the pro day circuit and how teams navigate through it.

Hand
-timed 40-yard dash metrics aren’t as appealing for scouts and evaluators, but there’s a reason schools stick with them, and it’s fairly simple. Because a person times these runs with a stopwatch at the 40-yard mark, they’re more susceptible to human error and minute delays in response.
The result? Generally, you get faster times.
It’s a known imperfection of the process surrounding pro days, but it’s one that’s here to stay. On top of stopwatches being cheaper than laser technology, they also provide the best numerical result for players. And because pro days are dictated by each individual school, putting prospects in the best position is what matters most. Arizona State football official Markus Alleyne echoed these sentiments in an article in the Sports Business Journal in 2021.
“
Lasers are always slower, but any advantage that we can provide our kids, we’re going to do that. So we make the decision whether we’ll hold [the pro day] on grass or the turf. Turf is faster than grass, so we hold it on turf. Inside or outside? Inside has more regulated conditions, so we hold it inside. We try to give our student-athletes the best advantage possible."
