If you don't cross 180 by July 31, but have at least 100, you'll remain Silver and 100 XP will be deducted for a new qualification year ending July 31, 2024. If you don't reach 100, your XP balance will be zeroed and you will lose status.

If as a Gold, after deducting the 180 XP to start the qualification year, you cross 300, you will likewise start a new qualification year as a Platinum with 300 XP deducted. If you finish that qualification year with at least 180 XP, you will requalify and have 180 XP deducted. Otherwise you will drop down to Silver: the lesser of 100 XP or your balance will be deducted.

Likewise, if as a Platinum you finish with fewer than 300 XP, you will drop down to Gold with a rolled over balance of zero to 120 XP.
