 If you want to, you could even drill down further with some manual binary search to find the exact byte when the break first occurs.
 
-The idea of this script is that each of these printed numbers take up exactly 6 bytes in the buffer, which you assure with the format specifier in the f-string that you pass to `print()`. When the buffer gets filled up so much that it needs to flush during the execution of your script, then you run into the break in the printout, caused by the call to `time.sleep()` executing. Finally, when the script finishes execution after the break, Python flushes the rest of the buffer contents, which prints the remaining numbers to your terminal.
+The idea of this script is that each of these printed numbers take up exactly 6 bytes in the buffer. This is assuming that you're using an encoding in which numbers and spaces take up one byte. If so, then you can make sure each length is 6 characters with the format specifier in the f-string that you pass to `print()`.

+At some point the buffer gets filled up so much that it needs to flush during the execution of your script. After it's flushed, it'll begin to fill up again. Ideally before it fills up again, you run into the call to `time.sleep()` executing. Finally, when the script finishes execution after the sleep, Python flushes the rest of the buffer contents, which prints the remaining numbers to your terminal.
 
 Finally, you need to subtract from the current value of `SLIGHTLY_TOO_LARGE_FOR_BUFFER` because we assume that the buffer flushes continuously when it gets full, which means that whatever is in the buffer when the script is done should represent a full buffer.
