Inquisitions Post Mortem Edward III

Here are some questions for those familiar with Inquisitions Post Mortem
(IPM).
I understood that IPMs concerned tenant in chief. So I tried to understand
the abstract in the document

"Calendarium Inquisitionum post mortem sive escaetarum" vol 2(1808) J. Caley
and J. Bayley,
concerning Robert Jorce (in 1371) saying :

anno 45 Edward III N°33 " Nullas tenuit terras in Comm' Notts" meaning " no
land held in Notts."

I suppose a person named Robert Jorce died at that time (1371) but How comes
a tenant in chief had no land?
I suppose the N°33 refers to the IPM which could be available somewhere
probably the Nat. Archives.

I am not familiar with the 1808 work, but if it only presents extracts
from IPMs, perhaps it was just saying that he held no land in
Nottinghamshire - i.e. he held land in chief elsewhere (did Caley &
Bayley focus on Notts by any chance?). Alternatively, perhaps there
was some claim to be a tenant in chief, and the Inquest found that it
was baseless.

You are right in saying that No 33 45 Edward III refers to the IPM
record itself. A look at the published calendar entry would be
instructive - anyone have quick access?

The escheators were more successfull with his cousin also called Robert died
few years after because they found a manor of Burton Jorz.

Thanks for your comments.
