In theory:

jtag_khz = cpu_khz / cycles_per_each_bitbang_pass

cycles_per_each_bitbang_pass = delay_iters_per_pass * cycles_per_delay_iter + bitbang_cycles_without_delay_per_pass
  = cycles_per_delay_iter * (delay_iters_per_pass + speed_offset)
where speed_offset = bitbang_cycles_without_delay_per_pass / cycles_per_delay_iter

jtag_khz = (cpu_khz / cycles_per_delay_iter) / (delay_inters_per_pass + speed_offset)
  = speed_coeff / (delay_iters_per_pass + offset)
