Mismatch between TCPTO formula and example in datasheet?

When I try to calculate the TCPTO for W5500 from formula on page 39 of datasheet version 1.0.9, using the values given in the example (RTR = 2000 and RCR = 8), I get for the second term: (𝑅𝐢𝑅 βˆ’ 𝑀) Γ— 𝑅𝑇𝑅𝑀𝐴𝑋 = (𝑅𝐢𝑅 βˆ’ 𝑀) Γ— 𝑅𝑇𝑅 Γ— 2^𝑀 = (8 - 4) x 2000 x 2^4 = (8 - 4) x 32000. However, the datasheet gives for this second term: (8 - 4) x 64000.
Am I wrong or should 𝑅𝑇𝑅𝑀𝐴𝑋 be: 𝑅𝑇𝑅𝑀𝐴𝑋 = 𝑅𝑇𝑅 Γ— 2^(𝑀+1)?
