Question about 2yr old racing

[wac]

1) why dont more tracks set up allowance races for 2yr olds? it just seems odd to me that the horse wins msw then goes into a grade 1-2 race against a bunch of other horses in the same boat. just seems to me like it make more sense to bring the horse along slowly but hey im not a trainer.
2) if a 2 yr old runs a low beyer in his/her 1st start are they basically a non factor moving forward? Reason i ask is there is a horse named Medal Count that ran yesterday at Kee in the stakes for 2 yr olds that was taken off T and i saw his 1st race thought it was pretty good but it came back only a 50 then yesterday he finishes 5th in a race that he basically ran around getting blocked and running up on horses most of the way then when it came time to go really wasnt anything there. so long/short should i forget about this horse or give him another chance? if so, how many more chances do these horses get?
