What the heck does "reach" mean?

<p>Aright.
Could someone please outline clearly the essential meanings of the ratings used by chancers?
Cause i have no idea...</p>

<p>Safety-You’re in
Low Match-Almost a safety, chance of random rejection
Match-you will probably get in
High Match-You have a good shot of getting in ~40%
Low Reach-You have a shot, but it’s not likely ~20-30%
Mid Reach-You have a shot, but it probably won’t happen ~10-20%
High Reach-Yeah right, you’re getting rejected.</p>
