Well, it could be a defect in the casting because AS has a challenging record of quality control, but most likely it's not.
Your water spot size is determined by the way the bowl is formed, so you can't
change it, per se, and of course in these days of low-flow toilets, the water spot is going to be smaller. Gone are the days of the swimming pool that you do your business into.
That said, however, there is a chance that the bowl is not being refilled to its designed level. (Just imagine that what you have in your toilet is a kitchen bowl that has one side a little lower than the rest of it, and a baffle blocking your view of that side of the bowl. If you fill the bowl higher than the side that's a little lower than the rest, the extra water will flow out of the bowl and onto the table. In your toilet, that water runs over the "weir" of the trapway, down the toilet trapway and down the drain. It will fill higher than its "natural" level for a moment if you pour water in slowly, but will settle at that lower level after your stop.)
A simple way to tell whether the bowl is being filled to its designed level after you flush is to get a pail of water, and pour it slowly into the bowl so that the level rises, but not so fast that you cause a flush. You will see the level rise, and then recede when you stop pouring. The level that it settles to is the design level. If your toilet isn't refilling to that height after a flush, the usual culprit is a refill hose that has become detached. The refill hose runs from the fill valve to the overflow riser (which is the tube that the flapper is next to). It should be clipped to and discharge above and into that riser. If it doesn't, then your bowl isn't being properly refilled. If the tube is properly-aimed but isn't properly filling the bowl, then you can easily replace the fill valve yourself. We recommend the Korky MaxPerformance fill valve, Model 528MP, which has a silver cap on it. This valve allows you to adjust the percentage of water that goes down the fill tube, and you set it so it routinely fills the bowl to the right level at the same time as it finishes filling the tank and shuts off.
