Hi Sentania,
The SMALL frame will be perfect for you - ESPECIALLY after you change the stock stem to a 100/45. Although a Medium frame will be good as well, the components of the frame are so adjustable that it may simply boil down to aesthetics. A small frame would show more seatpost and one additional spacer (ala Chris Lieto) while a medium frame will look more aero with one less spacer. Of course a medium frame will have a longer wheelbase but will you really notice a 1.5 cm longer length in a bike. I did some comparisons based on what you stated in earlier posts and check out both our stats:
Sentania
Saddle height: 740
(APS) Arm Pad Stack: 610 (could lower)
(BBS) Base Bar Stack: 580
(APR) Arm Pad Reach: ~495 (On Adamo ~520)
(BBR) Base Bar Reach ??

I am 5 feet 9.5 inches but my inseam is freakish long at 85 cm so my saddle height (BB to top of saddle) is higher than yours by at least a centimeter. After riding this thing for more than 600 miles I ordered the longer 100/45 stem to replace the stock 60/45 stem. The stock stem was actually fine but I like riding on the nose of my saddle (so the boys can hang out) and when doing so I feel I want to be a little more stretched forward. So I believe a new 100/45 stem will do the trick. I also removed just one spacer from the spacer stack and I really like the look looked of stacked spacers in the Speed Concept. Notice a lot of Tour de France pro riders have high spacer stacks too because their base bar sits so low. My base bar sits low which is the way I like it.
Once again the Medium would be fine for you but I always believe that between two frame sizes, one should err on the lower side. If you look at Lance and Lieto's SC frames they look quite small on them with a lot of seatpost and stems sticking out. By the way, I immediately replaced that 170mm crank for my 175mm. Finally, you won't regret getting the SC over the P3. I won't even discuss why. Just trust me.
