Weighted average for PSLF counts

If I am unable to consolidate my loans prior to 12/31 I understand a weighted average will apply for PSLF counts. I’ve read the example with 30,000 @ 80 + $30,000 @ 0= 40 eligible months or similar but I can’t figure out how to extrapolate the math to my situation. For example would $200,000 @ 80 months+ 2,000 @ 0 months still= 40 months or is that where the “weighted” applies? Thank you for any guidance.
