Hi- I am new to punting, new to Ozzie and new to this forum... so bear with me?

Just a quick question- as I know nothing about weight handycapping:

Horses differ in sizes. Do "they"(stewards?) consider that when weight "penalties" for past performances are determined? For example- two horses with absolute identical records; the one is xx hands high, the other xx+5, and the second one thus weighs in at 20 kg more. Do they get identical weights?

I would think that if they do, the heavier horse might be favoured as percentage wise it is less(of his total running weight everything up?)

Also, looking at barrier influences- Propunter does not give stats as wide barriers are not always filled- depending on the number of runners/acceptances. I cannot see why not, as it can be given as a percentage of starts. Obviously the higher draws will be less accurate because of lower numbers, but percentages could still be reasonably valid eg % tote-favourites which won from particular barrier... etc etc etc
In some instances draws could be very important- and such stats would help to choose between possibilities?
