Yes, it is not one or two day off form for him, 
he has not done well from 2019 World championship.

However he is still among the best in sg, he has rights to represent sg,
I do not see why he should not be chosen unless he does not want to.

but it is better for him to reject.  at least he can keep the record.

he and his coach should know that he could not get into final, based on the daily training record, don't tell me that they never measure the timing.

he is just trying the luck.

but for olympic swimming event, luck can only give him 0.1 sec the most.
