The bulk update request #8990 is pending approval.

create alias larger_prey (985) -> smaller_pred (1248)
create alias smaller_prey (4321) -> larger_pred (5344)
create implication larger_pred (5344) -> size_difference (344076)
create implication smaller_pred (1248) -> size_difference (344076)

Reason: These pred/prey size tags are relational. It does not make sense that larger_pred -smaller_prey is a non-empty search, much less one with 16 pages.

The first two should be aliases, not implications. Larger prey means smaller pred, having both tags is redundant.
A bidirectional implication should always be an alias (is a circular implication even possible? That seems like it would break something, since the tag is then implying itself).

No, the BUR will error when approved

I see. My bad, I'm new to the BUR stuff.

I changed the BUR to set the prey size tags as aliases of the pred size tags.
