Please note that while we’ll always endeavour to make our estimates as accurate as we can, there is often unforeseen complexity and unknowns that make truly spot-on estimates nigh on impossible (if that wasn’t the case, a robot could do our job. Maybe one day....).
All that is to say, we may occasionally get features which take less or longer than our estimate, but as mentioned , we’ll do our best to communicate this timely and adjust our planning accordingly.
