I wouldn't put much faith in those TWU power and sweet spot comparisons. There are a lot of obvious discrepancies when you compare racquets. In fact , just look at the default comparison. Does anyone believe that the Wilson BLX Six-One Tour is more powerful and has a bigger sweet spot than the APDGT? I used to use the APDGT, and the power and sweet spot are huge. I switched to the PK Ki 5x, which has one of the highest power and sweet spot ratings on the graph, but I know that both are nowhere near the APDGT, which was actually too powerful for me.
