Using double sided two way ranging (DS-TWR), the position reported is the average position of when the 3 packets are sent. For example, if a tag moves 10 cm between first and last packet, and the turn around times are symmetric, then the reported position will be a 5 cm shift from first packet position.
High bit rates and short preambles increase speed tolerance well above typical needs. You can make it work even up to jet airliner speeds if you want, but there’s no practical need for that.
Using short turn around times reduces the movement between packets and also reduces the clock drift errors, so good all around.
