I feel that there is a window, the importance of it is what's at question. If you consume whey/whey+Carbs immediately PWO the glycogen replenishment is far superior to any other time (within an hour) but unless your diet and training are on point, it is putting too much focus on micro factors and not enough on macro factors. 

Post workout, have an MTS Whey + Carb 10 shake immediately after training

Progressive Overload
