I suppose the answer to that is it depends on the terms and how interest is compounded. Our loan is a daily calculation, I can pay our loan before the due date, advance the next payment and pay slightly lower interest since there will be less principal on a daily basis. Said slightly differently, I could make a payment today and a payment tomorrow, both would count as a payment, advance the next due date for me and tomorrows payment would only have 1 day worth of interest.

OP - In the example you gave, AFAIK the account would show in good standing as long as it's paid on time, and it'll show up effectively as good standing, but there might be a notation that a payment was not due on a monthly payment tracker (when I used this tactic on student loans, that is how mine showed). If you pay 25K what is the responsibility on paying the remaining 5K - did you effectively advanced your payments for some number of months? If you make a partial payment, does it count towards the next payment or do you need to make a payment in full in order to advance the next payment? Any prepayment or early close penalties? Read the terms you got with the loan, to be sure as results may vary based on terms (for example, I have a early loan close penalty in the form of an incentive I was given upfront for taking the loan being clawed back in the first 18 months).
Also as an aside, not sure what that money is doing if it is not paying off the principal early, but keep that in mind (understood 4% is higher than desirable).
