-This will run 1 or 10 millions RandomX hashes and print the time it took. First two commands use Monero variant (2 MB per thread, best for Zen2/Zen3 CPUs), second two commands use Wownero variant (1 MB per thread, useful for Intel and 1st gen Zen/Zen+ CPUs).
+This will run between 1 and 10 million RandomX hashes, depending on `bench` parameter, and print the time it took. First two commands use Monero variant (2 MB per thread, best for Zen2/Zen3 CPUs), second two commands use Wownero variant (1 MB per thread, useful for Intel and 1st gen Zen/Zen+ CPUs).
 
 Checksum of all the hashes will be also printed to check stability of your hardware: if it's green then it's correct, if it's red then there was hardware error during computation. No Internet connection is required for the benchmark.
