The light red area is the 5Nd, so if you were mining since the beginning of that area (or before) then you are now fully ramped up.

Again, as a reminder to all, the 5Nd 'ramp' isn't a time interval, it's an amount of hashes - specifically 5 times the network difficulty.
Since the pool hash rate changes around quite a bit, the 'time' for the 5Nd is quite varying
