14 form Rs
11 Honorable Mentions
I entered the contest with my first "original" story in December 2007. It garnered a plain form R. To be fair, it's an actual Firefly knockoff which I scraped the serial numbers from--as in, it was fanfic first before I rejiggered it. That being said, that story has spawned four others in the same series, three of which have found homes, two of which have found two homes. Publisher's Freaking Weekly even said something nice about one of them!
My next entry (March 2007) also garnered a form R. However it was also my first pro-rate sale, to Cosmos.
My next three entries all garnered Honorable Mentions, though they weren't calling them that yet for the very next one. I'm not going to go through them one by one. That would be ridiculous. However, for your elucidation:
2007: 4 entries (3 HMs)
2008: 4 entries (3 HMs)
2008: 2 entries (no placement)
2010: 4 entries (1 HM)
2011: 0 entries (The Year Roleplay Ate My Brain. Whoops.)
2012: 3 entries (1 HM)
2013: 4 entries (1 HM, 1 Finalist)
2014: 4 entries (1 HM, 2 SFs)
2015: 4 entries (1 HM, 1 WINNER)
The moral of the story? NEVER GIVE UP, NEVER SURRENDER.
Also, find your niche and play it to the hilt. My last six placements were all werewolf stories, except one, but it had werewolves in prominent secondary roles. Two of those were Finalists, and two were Semi-Finalists. Dave Farland (famously) hates werewolf stories--he said so in the blurb for my novel! You can make someone look at something they don't like twice if you just do it well enough.
