API-650 11th Ed Addendum 2 - Section V.8.1
(OP)
In the "US Customary Units" section, the 3rd definition for "psi" reads:
[Pe + 10] for wind .... when Pe is greater than 15psf, but "psi" need not exceed 2.5.
If Pe is greater than 15, then the summation is greater than 25. So we're going to reset 25 to 2.5 ? Perhaps there is a divisor missing from this equation, maybe 10 or 12 ?

I've also a problem with App V, especially with formula V.8.1.3.
If the value of Ps=W+.4Pe and greater then Pe (i.e. Pe=0.5kPa), do you use ψ of condition 1 of V.8.1?
