For 3 B Ranks it is 0.5 * 190 + 0.5 * 190 + 2880 - 0.8*190 = 2918 exp., or 2918 / 1428 ~ 2.04 points, for 3 S ranks it is 190 + 190 + 2880 = 3260 exp., or 3260 / 1428 ~ 2.28 points. No rounding. For the Sub Route it's something similar, but to get the average points per run you need to look at your statistics (depends on the rank distribution).

So yeah, (2500 - 780) / (3260 / 1428) ~ 753 5-4 runs (all S ranks, all EO and disregarding other gains), or ~25 runs per day for 30 days straight. Also note that ~10% of those runs will be retreats, so you need more runs, each run is ~5 min, or ~10 runs per hour, so 2-3 hours per day (or 1+ hours per day twice).

Soon™ there will be Ranking article that will explain everything in details (with tables, graphs, compositions, etc.).
