Laughed pretty loud about learning Russian in 24 weeks for B2 level. In russian schools language course for B2-C1 level is done in 4 years (A1/not-so-A2 is done in elementary school, but it's included in that course IIRC) with minimum of 245 hours per year, 4*245=980 hours. Nowhere near 600.

Russian and all the slavic languages are classified at 44 weeks, not 24 weeks. FTA, the hour estimate is 1100, very close to your 980.

My bad, I should check my color blindness.
