Couldn't agree more. They're looking like scoring at around 90 runs per session, notwithstanding the boost that might occur if someone were to warn Pietersen that he was in danger of being dropped, so would be approaching 300 clear by lunch on the fourth day.
In reality, the biggest issue is getting to stumps tomorrow - we know how quickly these Indians heads go down, and I think that that would be too big of a psychological barrier for them to successfully recover.
