Maintenance Dose Confusion

I own two books from Jim and have used MMS in the past. Now I got the mail from Jim recommending the maintenance dose of 6 drops a day. I still have several blue bottles of MMS and Citric acid from a few years ago and I have both also in powder form for reserve.
The instructions were always 5 drops to 1 drop MMS. It appears that Jim now says its just 1 drop activator to 1 drop MMS. It does say 40% Citric Acid. Mine is still the older less potent version. Can I just use the old Citric acid and just more drops?
Thanks for your reply

Yes you can still use the 10% citric acid as activator, activate for 3 minutes. The new protocol uses 50% citric acid and activation is only 20 seconds. When you mix up your next batch try it - it's much quicker
