Retaining wall Drainage

Hello all.
I just installed a 3ft high on one end 1 ft high on the other end retaining wall along my driveway and have some questions. The driveway slopes toward the retaining wall so the water flows that way. I constructed the wall by cutting into the slope of the grass that was building up to the driveway. I made the base for the wall level and used step ups where i could to keep me from digging a huge hole, as the slope also sloped up from the starting point. So I was dealing with a horizontal slope and vertical slope. the retaining wall is going to give me level land next to my driveway, hence why I built it. Now I laid in a good 5-6 inches of M10 granite sand and packed well. Then right behind there I laid 4 inch perforated pipe with a sock over it and then vented it to daylight at the lowest point. The wall is only about 25 ft long. I backfilled with 3/4 granite rock on top of the pipe and plan on putting decorative rock on top to finish it. Now there is a chunk of dirt I did not disturb during the contruction, about a 2 ft wide section from the driveway to the pipe the entire length of the wall. Now we just recently had some heavy rains, 1.75 inches in about 3-4 hours time. I was wondering if water should be pourinig out of the drain tile I laid? It seems to me that it is doing its job by carrying the water away from the base of the wall, but most people said that it would be trickling out. I am assuming that it is from the ground being so saturated that all the water is just running off and filling up my pipe and draining.
