Can i do more than 9× at once? Like 54? Or do i have to do *only* 9 reps of each letter?
Yes!...
It's been stated by HP.Cobra that he and a few others like to "stack" the RTRs. So yes go right ahead but I suggest for a few days start at a lower number and get used to counting higher. The RTR becomes more powerful even a 1, 3, or 9 is powerful because of all the damage done on previous multiple RTRs plus the sensitivity of the witchcraft language of hebrew. But...you can "stack".
For example 18, 27, 36, 45, 54 etc.etc. of course your free to pump as high as possible but as a learning experience you can speak the words out and learn how to handle a higher rep.
Also do keep in mind "stacking" saves some time as well. For example for me 7-10 minutes for a single 9 rep RTR but about 11-13 minutes for 18, 27 area. So in essence by not doing multiple 9ers your kinda saving some time combining it all together give or take an extra 2-3 minutes or so for each multiple. So I figure doing 54 reps like you want to do is probably gonna take you nearing 17-20 minutes or so.
And yes if you wish to consider it a single time as not to burn yourself out. One high rep can be done for the day and your done. Usually with lower reps you can spread it out over the day.
BTW generally speaking 54 is above the normal range of RTRs the JoS recommends to people. JoS recommends about 3-5 RTRs so basically 27-45; 9ners or "stacked" 27-45; basically your doing 6 RTR rep range so just one more above the recommended.
So keren824 and any other person reading this you CAN "stack" F-RTRs if it makes it easier on you. Again like high rep range RTRs of the past doing 54-108-216 you CAN "stack the F-RTR".
