Jousting records (5)
I believe the answer is:
lists
'records' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for lists that I've seen before include "Ancient tournaments in which knights jousted" , "Rows of data" , "Silts up and leans over" , "field of combat" , "Heels; catalogues" .)
