I have noticed that o my Toto drake and entrada toilets that if the lever is not pushed down all the way and held momentarily the water spot does not refill fully.
Leave it alone. Push all the way and release. What you get on refill is what you are supposed to get. Drain the tank (which you're not supposed to do) and you will get more refill to the bowl, because what goes in the bowl is a fixed percentage of what goes in the tank.
When you say the water spot doesn't "fully refill", I take it you mean the little porcelain depressions don't get full or something. What a "full" refill is is whatever fits in the bowl before flowing over the weir. A bowl has a "settle level" and it will never let more than that remain in the bowl, regardless of how much you put in it. The reason is obvious:
Now if your toilets are tipped too far backwards, then it will lower the level in the bowl a bit. But assuming that they were installed properly, the water spot is what it is. That said, all bowls if you refill them a little too much, slowly, they will go a little higher, but the excess water will then drip over the weir. After you do what you're doing, does the water stay at that level, or does it recede? I'm guessing recede. If not, then you need to make sure that the toilet is properly-adjusted.
