RHF100 inconsistent values for 100 krad characteristics (1.8mV or 0.5%)

[MJesk.1]

RHF100 has following characteristics for reverse breakdown voltage tolerance:

1.8mV / 0.15% for 240hrs burn-in (Table 4)

1.8mV / 0.5% for 100krad (Table 6)

4.2mV / 0.35% for 300krad (Table 7)

This data looks very inconsistent. What is correct value for the 100krad reverse breakdown voltage tolerance?
