I had a look through that and couldn't find the answer.
The quote currency of EURJPY is JPY so the P/L from any trade will be denominated in JPY. That must be converted to USD in your case. The exact rate you get when your P/L is converted in to USD depends on your broker and when they do that conversion.
Here's an example:
USDJPY=100, EURUSD=1.5, EURJPY=150
You go Long 1 lot EURJPY
100,000EUR = 15,000,000JPY
say JPY falls 1% against EUR and USD
USDJPY=101, EURUSD=1.5, EURJPY=151.5
You close your position
100,000EUR = 15,150,000JPY
profit = 150,000JPY converts to about 1,485USD
So on that 1% move you only got 0.99%.
Conclusion: It's not worth worrying about!
