Not sure what you mean by "now appearing" but just ran a quick test of faves under $3 for last year.

all faves
Win SR 40.50% LOT -3.96%
Place SR 71.50% POT 3.97%

first 4 races
Win SR 41.5-60% LOT -3.62%
Place SR 72.80% POT 5.15%

This appears consistent with what we have discussed in here often - the bias in first 4 races.

Just a note...
I looked at one of my faves systems.
In January last year it made a small loss.
In February it broke even and for the rest of the year it made a profit every month.
If one had been standing there in Feb last year and looking back over a couple of months, one could have said that my fave system wasn't working.
Even very successful methods can have quiet times for a month or two.

Hope that helps in some way...
