You're correct in that there was no 51.3 test charge. I think any reference to that weight was an assumption that it might be a good one based on what 51.2 and 51.4 showed.
Again, though, started getting increasingly hard bolt lifts beyond about test #6 (50.8+)...
That was my assumptionon 51.3
I did however miss the "bolt lift" above 50.8 so would not look up there
