A spotless record can just mean you only played the easy levels.

A clean record has two possible explanations and they point in opposite directions. Either you are very good, or you have been careful to enter only the things you were already going to win. From outside those look the same, which is why the easy bracket keeps getting picked.

Find your most recent real loss. If you cannot locate one in the last few months, that is the finding. Enter something this term where the result is genuinely not settled in advance.
