I'm somewhat familiar with how to calculate branching ratios. I know that they are calculated as the ratio between the decay width of a specific decay process and the total decay width of the particle (as said in [this] 1 stack exchange post). However, I'm not sure how people are getting the values for the various branching ratio of the Higgs boson. In my textbook I have this table which lists the decay widths and branching ratios for the Higgs boson processes:

I was trying to calculate the branching ratio of the four-lepton decays: $$BR(H^0 \to l^+ + l^- + l^{'+} + l^{'-})$$

I used the values on this table and for the decay width of the four-lepton decay I used the decay mode width for $H^0 \to Z^0 f \bar f$. The value I got was $0.00276$. From what I've read the branching ratio for this specific decay is about $0.02%$, so my answer is not correct. What are the actual values used for the calculation of the four-lepton decay? Are there more than on this table?
