I think it looks good. 47, 50, 53% is a good place to start with bands. But your light bands probably arent adding 175lbs at the top unless they are short bands. My strong bands stretched to 6 feet come out to about 220, averages about 150, lights about 100lbs.
50, 55, and 60% are good weights to use without bands. Not with them. Everyone I have seen go 60% with 25% band tension moves A LOT slower than 50%, which completely defeats the purpose of pure speed-strength work.
With the dynamic effort method, you can really do whatever the hell you want to based on your weaknesses and your creativity. My next de squat cycle is with 50% band tension and waving 43%, 45%, 47%. I am doing this to peak for a meet in 5 weeks and also work on my strength-speed.
