Actually, hashrate is following price. Most miners always put their hash power into the coin with highest profit. Which will cause hashrate always proportional to the price.
Agreed. Also BSV is a good example that price does not follow hash rate. They have mined with a big deficit for months.
And PoW is integral of historical price. If BCH want to overtake BTC in PoW, it will have to have a higher integral of price than BTC.
