You don't really need many stats for 25nl because few people are pulling off anything fancy. The stats dcor says are standard seems fine to me. Fold cbet turn won't converge very quickly unless you play a lot. Other "standard" stats probably include fold sb to steal and won when saw flop.
One stat that I really liked was bet river%. This stats gives me a fairly good idea of who is betting for thinner value / pull off more elaborate bluffs (because most people play the river pretty straight forward). Do note that it does not converge that quickly.
