>So at the point where Europe was still recovering from multiple centuries of Islamic invasion
What do you want him to do, call from the early proto-industrial period?
What point do you think that would even make? Using balanced resource production and extraction systems, you can make a more sensible comparison. And yes, India was recovering from invasions and internal wars also. Everyone had things to deal with during that time.
Europe wasn't uniquely impaired. It would actually be boosted by the economy of the Americas and their connections abroad, so the best time to choose would be 1500 AD, before the price revolution, but after the Reconquista, unless you want Moorish blood tainting your perfectly-fair-economic-data-points.

Europe didn't have as large a population as India during this time. The soil is harder to work, they didn't use seed drills, and they had a winter season to contend with.
Even in the 18th century, Bengal would obviously dwarf any European counterpart (going by land area) just because it's high quality real estate. The Indus river valley is naturally fertile. Get over it.
