I prefer the term “Cool in, Hot out” but I subscribe to the general idea and always have. It depends on what you consider to be “Slow in”. That doesn’t mean creeping but there is a lot of time to be lost charging in too hard and a lot of time to be gained with a good fast exit.
You definitely should be hard on the gas before the apex of the corner, if you aren’t picking up the throttle until the apex you are giving up time and straightaway speed.
