In Hilti Profis value of Tau_k does not match value from ESR report

Reviewing the calculations from a report in Hilti Profis. I have threaded stainless stud 0.75 diameter with hammer drill in low temperature setting. In the bond calculation the values of Tau_k, (cracked and uncracked) do not seem to match what I see in the ESR. In the PROFIS calcs these are:
t k,c,uncr =2,533 psi
t k,c = 1,387 psi (page 4)
However, in the ESR, i see the following:
t k,c,uncr =2,130 psi
t k,c = 1,250 psi (page 18)
