English to Japanese Other Business/Commerce (general)

Every time I encounter the expression "price leakage", I only translate it as 価格の最適化 (potential to optimize price) by changing the sentence structure, as there is not direct translation for price leakage.
For example. "allocating sources of price leakage" may be translated as 「価格最適化余地を特定」.

I wonder if other people translate this phrase.

Thanks for your help in advance.
