+1 for Tepford, however, Jim always says principles.
So, start low (in your case reset), then either do 4th week deload or 7th week deload, and just keep on keeping on from there. You will see results over tiiiiimmmmmeeeee.
Also, and I think I can speak for many, there are good days, bad days and average days. Most training days are average. Every once in a while you hit one out of the park, and every once in a while you really stink one up. That's just part of the drill. Just keep on going. The next workout will likely be much better.
