TLC6983: Question about calculation with Blank Time Removal

Part Number: TLC6983

I'm studying the specifications of TLC6983.

I'm a little confused with here 9.2.1.5 Blank Time Removal.

" From Equation 3, 83.4-MHz GCLK frequency and 1.44-us line switch time, the calculated blank time is 0.572 ms
  ( 47737 GCLK), which is too long and brings black field. "

In my calculation refer to Equation 3, 

TBlank = 1 / 120Hz - (512 segment / 83.4Mhz + 1.44us ) x 30 line x 32 sub_period = 1.058ms

Please tell me what I missed.

Thank you.
