This read-create value configures the ABR Rate Increase Factor, which controls how much the allowed cell rate increases when a backward RM-cell arrives with congestion indicators clear, applied symmetrically at both local and remote endpoints. An admin tunes this to control how aggressively an ABR connection ramps its rate back up after congestion clears - larger values mean faster rate increases and quicker recovery of throughput. For example, on a connection where the admin wants ABR traffic to recover bandwidth quickly once congestion subsides, they would configure a larger rate increase factor here.
