I followed the saga from beginning to this end. When you say that you let the system run while you watched TV (or something), were you actually playing LPs during this time, or was the system just "on"? One point I failed to mention and which was not emphasized by others, either, is that many if not all cartridges DO require at least 5-10 hours of break-in from new, in order to max out the bass response, more so than for other higher frequencies. IMO, this is because the suspension has to loosen up a bit. I just went through such an experience with a re-tipped cartridge that had previously been "on the shelf" for many years. What you experienced and are experiencing may be entirely due to break-in, which means that the bass response may continue to improve over the next several hours of actually playing LPs.
I also agree with whoever else suggested not to increase VTF dramatically beyond the manufacturer's recommendation (+0.5g is dramatic) just to chase bass response. There is good reason to stay within the recommended range unless you have serious mistracking.
