In a data‑processing system the following decision rule is applied after each processing cycle: if the number of records successfully processed is greater than 80 % of the total input records, the cycle terminates; otherwise the system repeats the processing after correcting the flagged records.

For a batch of 2 000 input records, the first processing cycle yields 1 500 successfully processed records, 300 records are flagged for correction, and 200 records are lost due to corruption. After correction, 90 % of the flagged records become correct.

Will the system repeat the processing cycle after the first correction? Justify your answer with calculations.
