Wow seems great to me. I think it is all a matter of perspective. Not sure of your age, training background, available training time, etc. Your AeT and AnT are close, so great. Now it’s time to add intensity. Done properly, in conjunction with keeping your base work up, you will see speed increases. If you are a slow twitch muscle kind of athlete, it will take longer, but you will see improvements. Remember speed is many components, including strength, and given your numbers, you should be able to make progress. Also, don’t compare yourself to someone in an article. Yes there are some superior athletes that train using this method and trying to compare yourself without knowing if it is a fair comparison seems like a good way to get depressed.
