Okay, so here are the three issues as I see them:
1) There isn't any real basis for using "snail speed" here. Here's what the relevant part of our Calculations page says:
Sometimes even something like "time seems frozen" or that nothing moves is stated. Often these kinds of statements are hyperbole. However, should that not be the case one may assume that the apparent speed of the reference object is less than or equal to
0.00275 m/s, as that's the top speed of garden snails, animals that move so slowly that they appear to be nearly frozen in our perspective.
There is no statement of the rubble being frozen relative to Boros, and we can't really judge such a thing from a static manga panel unless it is over an extended sequence.
2) The speed that is being used for the rubble that is "frozen" is highly questionable:
This velocity of
59.34 m/s that has been calculated is the end velocity of the falling rubble after starting from a position of
0 m/s velocity and falling down
179.55 meters.
How was this value of 179.55 meters found? Well, it's the distance from the POV of this panel down to the ground / floor:

In other words this is the speed that the freefalling rubble would have...
when it reaches the floor.
So why is this speed being used for rubble
that is in front of Saitama here, a considerable distance above the floor? The rubble would need to fall a lot further than where it is to reach the speed that has been calced.
3) The aforementioned POV shot getting the distance from the POV of the panel to the ground/floor is from a perspective that is well above the crater in the pillar that Saitama was punched into and from which the rubble is falling... So even if this distance were to be used
somehow, it's not even taken from the starting point of where the rubble would be falling from which completely negates using it in a freefall calc for that rubble.
So never mind the fact that "snail speed" is highly questionable here as an assumption, the speed of the rubble that has been calced has a couple of glaring issues with it.
Those are the problems as I see it.
