This might not be the most helpful thing, but it's probably better than nothing so I'm going to include it. It's not really the stats themselves that matter, more the base stats, but this is for all the people wondering what your spread translates to at level 5. The formula for stats at level 5 are the following:
HP:
(((2 x Base + IV + (EV / 4)) x 5 / 100 + 15)
Other stats:
((((2 x Base + IV + (EV / 4)) x 5 / 100 + 5) x Nature)
Base is the base stat
IV is the IV value (just use 31 for a start)
EV is the number of EVs invested (just use 0 for a start)
Nature is 1 for a neutral nature, 1.1 for a positive nature, and 0.9 for a negative nature (just use 1 for a start)
(Note: after every division, the total is rounded down.)
Once you've looked at the stats with 31 IV, 0 EVs, and a neutral nature, its easy to figure out everything else.
On that note, my advice for figuring out a believable stat spread is to look at examples of prevos, especially the families of Pokemon we think resemble the Syclant family. Look at how much the base stats change, and figure out believable jumps. The final stats aren't so important (as we don't care how competitive Syclar is), so do your best to figure out a spread that seems true to the game.
