Glad you got a calculator. This way you won't have to worry if the info you find on the net is accurate
I wouldn't pay for a separate account either in your position-heck I don't pay for one at all but the calcs are well worth the money. They handle everything anyway, including that you can put in your info and get your daily target also (if the new PP are the same, I haven't actually set eyes on one). I'm not an official member of WW just doing it on my own too so a small notebook to track and points calculator off ebay were my only investment.
Here's to new beginnings for you, I hope you find success in the plan <3
