Too early to say anything, it depends on the weather as well. If there is overcast throughout, the pitch will deteriorate faster. But if there is sun throughout, it could become a batting paradise breaking down late on day 4. There is a tinge of green on this pitch with hardly any cracks and it's showing no signs of deterioration as can be seen by the lack of footmarks by the bowlers. So it's well put together to last 5 days. The thing with Windies pitches is they're spongy because the clay is old but well put together at the same time with hardly any cracks. There is grip available for spinners and spongy bounce during the early days that can be exploited by overspin. Someone like Jadeja can be dangerous because of the pace he bowls at.
350-400 I'd say is a competitive score.
Probably late day 4.
