If we have a testcase containingabc, andbc is the reduced result (--char mode, strategy=minimize), the run will look like this:

bc ➡️ interestingc ➡️ not interestingb ➡️ not interestingStarting another round with chunk size 1c ➡️ not interestingb ➡️ not interesting

This final round of chunk size 1 will always be unneeded as long as the reduction in the previous round was only at the beginning. I think this will be true for all atom types (line/char/symbol) and strategies.
