I sent you a PM. I have citizenship since August 2013. I renewed my tourist visa for 13 years with trips to Colonia every 90 days and a few times at migraciones. I intended to stay in Argentina from the day I arrived, February 3, 1999.
The only way you're going to know about your "chances" is by consulting a lawyer who specializes in the area and has been successful in other citizenship cases. It is something that you can do yourself, but you need an excellent command of the language. You need that anyway for the language test.
I suggest consulting with the lawyer who helped Arlean Kelly get citizenship. Search the forum for his name and telephone.
