Full Round of Trials Starts This Week!

Luckily for me its our last week of lawn bowls and North are playing on the Friday night so I don't miss any games.
Exactly what can be garnered from trial games?
Its a long standing question but if it helps, here's the results from all trial games last year:
Saturday 4th February
NAFC 14-6 90 d NTFL 9-13 67
Friday 17th February
Crows 19 - 7 121 d Norwood 8 - 7 55
Saturday 4th March
Norwood 9-10 64 d Port 9-8 62
Friday 10th March
North 19-18 132 d Sturt 11-4 70
Saturday 11th March
Eagles 23-9 147 d South 13-16 94
Port 11-16 82 d v Glenelg 9-2 56
Norwood 14-14 98 d Central 13-7 85
Bye: West
Saturday 18th March
North 13-14 92 d West 13-8 86
Eagles 11-14 80 d Central 8-7 55
Sturt 13-8 86 d Glenelg 9-16 70
South 22-12 144 d Norwood 8-10 58
Bye: Port
Satuday 25th March
South 20-12 132 d Port 19-10 124
Eagles 18-10 118 d Glenelg 11-10 76
West 17-13 115 d Sturt 9-6 60
Central 12-10 82 d North 11-14 80
Bye: Norwood
If you add the wins up (disregarding the NT and Crows game) it would have read:
Eagles 3 wins
North 2 wins
South 2 wins
Central 1 win
Sturt 1 win
West 1 win
Norwood 2 wins
Port 1 win
Glenelg 0 wins
With Port already beating Norwood can we deduct that Port will improve on 5th possy and Norwood will go backwards from their 7th possy (and that doesn't even take into account their poorer result against the Crows this year)?
