It is more difficult than you think to fool the handicapper & stewards. They have a lot of experience in detecting sub-par performances and athletes who do so need to be very careful as the penalties can be severe.
Most athletes put their faith in the handicapper by running regularly, consistent and to their best every time so that the handicapper can give them the mark they need to win a race.
HOWEVER if an athlete has a canny coach who knows how to flatten an athlete for lead up races but still have the nous and ability to have the athlete peak and in PB shape when it counts, then, yes, slow times can be fabricated to perhaps ‘encourage’ the handicapper to offer a bigger handicap.
The knack is peaking the athlete when it matters and the history of Stawell is littered with anecdotes of athletes who failed to perform when it mattered.
Alozie has run sub 10.2 hence the mark of 0.75m. Problem for Alozie is he seems to be very much out of form and probably won’t make the semis. He does have the invitation backmarkers to run in on Easter Monday - a one off race for the 6 fastest sprinters (backmarkers) at the meet.
