Hey, Bradh7 (can I call you Brad?), welcome.
I think I know the T-Nation thread you're referring to so if you are asking this in relation to the stuff in "singles scene" then you have misunderstood at some point.
You do NOT need to worry about increasing total workload in the fashion you are describing. This is not a volume/workload thing. That is something that should be done separately following different methods.
If you are doing a cycle of singles, your relative max may or may not increase as you go along. The goal is to lift to your best ability on each day, so it is reactive or like someone in that thread said…"autoregulated"..although I think that is a overly fancy term to use for training. A whole singles cycle is meant to help increase your 1RM. It is not necessary to expect huge increases during each session. Now, you are obviously not a novice but singles really are not needed for novices OR those who can increase their weights and/or workload by a big margin on each and every workout at these high intensities.
Given that, if you are capable of increasing your weight each workout and you want to use singles (it's more fun, after all), that is great. But you still run it the same. If your relative max increases each time. Great. If it doesn't, or even if it drops a little on one session compared to another, that is okay too. The idea, then, is to have the subsequent singles be as high above 90% of the relative max, on THAT DAY. If most all of the singles end up being just at 90%, fine. If you start out higher, drop back down, then go higher again as you're doing the singles, that is fine too. So, you are not worried about total workload and increasing that workload next workout. You treat each singles session as a stand alone, with a given rep target (number of singles) wherein you do the best you can that day. The whole cycle, taken together, is an opportunity to simply perform a high number of lifts at a very high percentage of your relative ability.
There are numerous threads and explanations where I've explained the reason for this and I'll be happy to elaborate.
After someone does a single cycle, and supposing they then test at some later point and get a new PR, then may be a good time to work on increasing their tolerance at a weight range closer to that PR. So then would come higher volume and workload increases. That's the way we do things, anyway.
Ashiem was asking just for more of a history of the kind of training you've done up to this point and for more elaboration on what you're doing right now since what you described doesn't really "jibe" with the way we think about singles here. I don't know if you're trying to encorporate some other concept into it such as linear progression "volume/intenstiy" stuff like 5x5 programs or what but I would advise against that.
