I dont know from experience (though Coach @FRANK and @Jake do 
), but can imagine she has very little concern about your watts lol. Thats what FasCat is there for! #dadwatts
If you arent racing until late fall, I would just restart your 16 week plan (which ends with SS part 2) to make sure you reap all the gains from the gym. From there you could do SS part 3 and even part 4 if things get pushed back even further. Then 6-8 weeks out from your first A race, jump into race specific intervals (8 weeks if the interval plan does not include a taper). While doing your SS plans you can just train through those local races, using them as your SS group rides on the weekends. The Wed/Thu night worlds could be tricky if you are going too hard. We have a helpful forum thread here that touches on this. Feel free to chime in there with any questions if you like!
