The "Summary for the top 5 players" comes from the summary tab.

That's confusing to me because the Summary tab provides an overall tournament summary, but nothing about specific players (other than actions, or who won, or first player out). It doesn't provide a points summary of the top 5 players. Regardless, I understand that these are the point totals awarded to your players.

If you've got "Points for hit" set to anything besides 0, you're double-awarding points, because your Points for Playing formula includes the "nh" variable (2*nh). Basically, the formula awards two points per hit and the "Points for hit" field is awarding additional point(s) for a hit. If you have the "Points" field set in the Buy-in, then there's an additional point that also doesn't reflect in the Points for Playing formula.

I'm going to go out on a limb and say you've probably got "Points for hit" set to 2 and "Points" for the buy-in set to 1. That would explain the discrepancy for all players. Take Brandon as an example. The Points for Playing formula yields 37 points. With "Points for hit" at 2, he gets an additional 12 points for his hits. Plus an additional point for buying in yields 37 + 12 + 1 = 50.

FYI, the field "Points for hit" and "Points" in each of the Buy-in, Rebuy, and Add-ons sections are intended to be an easy way to award simple points. The "Points for Playing" field is provided as a much more advanced way to award points. While they can certainly be used together, there's no need to as "Points for hits" and points for buying-in, rebuying, and adding-on can all be included in the Points for Playing formula.

If you set all of those various fields to 0, then add a single "+1" to your formula, I think you'll be good:

(sqrt(n*bc*bc/tc)/sqrt(r+nr))+(2*nh)+1

The +1 represents a point for buying in.
