Figures going up and down (5)
I believe the answer is:
stats
'figures' is the definition.
(short for statistics)
'going up and down' is the wordplay.
I cannot really see how this works, but
'up and down' could be 'tat' and 'tat' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for stats that I've seen before include "Copies" , "information showing sporting performance?" .)
