If a player inadvertently makes a call he did not intend then he may change it {subject to being in time}. It matters not whether it is insufficient or not.
So if the player bids 1
when he means to bid 3
then it may be changed: it may not be accepted: and there are no UI problems because the player meant all along to bid 3
. If he did not intend to bid 3
then his 1
was not inadvertent and may not be changed.
Of course he may only change it to the call he intended. For example if the 1
was out of turn he may change it to 3
if he can convince the TD he meant to bid 3
, but it will now be treated as 3
out of turn.
