Lightly raced horses are a volatile bunch, and obviously 2yos are the most lightly raced bunch as a whole. The lightly raced ones are learning how to race, the effects of races, efforts, and gaining condition. Trainer styles and pedigree also have to be factored in assessing newcomers and lightly raced ones. There's little performance history if any, so it's difficult to tell when a performance will elicit a reaction.

The three above have raced 3, 2, 2 times, respectively, and none of them have regressed as yet. Each improved last time out to run a single digit effort. The fact that each got down to the sub-10 level quickly indicates that they have talent--2yos aren't fully developed physically, and although some develop more quickly than others (pedigree influence).

Wanna Runner ran two nondescript effort at Dmr and then exploded with big effort going two turns on about 12 weeks rest. Now he comes back 4 to 5 weeks later. Ramsgate okay 1st out but caught a dead rail (X adjacent the figure) so the effort might not been as bad as it looked and indeed 8 weeks later he jumped up about 6 points and enters here on about 6 to 7 weeks rest.

Refinery debuted faster than both above and improved 1-1/4 points 3 weeks later, about 4 weeks ago. He's a bit slower than the other two and shows more regularly races.

As a general rule, small incremental steps resulting in new tops are less likely to yield bounces, next time out, time off notwithstanding. For instance Refinery is less likely to bounce among the three since his new top is a small forward step and he proved he could handle a prior level not too far removed from the present one.

In this case, the two that made the biggest forward moves also enter with the most time off since that effort, more recovery time and they're faster and haven't been set back yet.

Hope this helps.
