GL with capping.
This is not true.
You'll be 1k short of your value because if you earn any conquest during a given week, you forfeit your conquest catchup bonus.
eg 2 players, A and B. Both have 18200 conquest on a given week.
Player A plays a random BG and earns 100 conquest.
Player B quit last year and hasn't logged on since.
A's cap next week will be 18200 with 100 earned. B's cap will be 19200.
