Bisection 2, 5, 10, 18, 28, 42, ... seems to give the positions of records in A246348 after the initial positions: 1, 2, 3, 5, 10, 18, 28, 42, ...

This easily follows from the pattern present in A246347, as from its fourth term onward, each two successive new records appear to have the same binary width.
