I'm worried that in this case all you have done is created a "blob" (for lack of a better term) of solder. A good solder joint is a hot one, and hot solder joints happen quickly. You may have just filled in the gaps without providing any increase in mechanical or electrical integrity.

I have a question, assuming you only screw down the lug, do you get a better connection on more finely stranded wire? Like good welding cable as opposed to the junk battery cable they give us?
