Like before, send in your stat updates as soon as possible, and you're still allowed to send them on Sunday.
However by Sunday and Monday we will do update checks. So if you want your overall stat gains to be approved by the Staff from the previous weeks, you MUST send these in. If you don't, well you'll only be as weak as last week. If you didn't send in one for the previous week, then I would highly recommend you to do so now.
After you send in one of these Stat Updates you may begin your training/sparring/training for the next week starting Sunday. If you clearly document your stat boosts in the Char Profiles sections, Grade my RP sections, or other relevant threads you may proceed with roleplaying before your Stat Updates are approved. If not, you'll have to wait until the Staff audits and approves your Stat Update of the week.
