Company I now work for says no need to adjust for wind effect as a tailwind allowance of up to 25kts is built into the Airbus Circling SOP.
How on earth does your Company think a tailwind does not affect an Airbus ground speed / timing down wind?

"5.4. Timing for Circling:
The timing Airbus recommends is
30 seconds from wings level, adjusted
for strong Head or Tail wind,
by reference to the ND wind indicator.
However, this is a visual exercise:
Timings are approximate only."
