The LitecoinBlockhalf website is wrong, since it's calculating the last 8064 blocks including pre-signalling blocks. That doesn't make sense does it?
Currently, SW is at around 6% with CSV support slightly higher. After F2Pool adds support, there will likely be more support from pools. Especially since we will be a lot closer to the 75% target for activation.
We also have something coming out on the Litecoin Core 0.13.3 release directly related to this. If you take a look at some of the commits from the past week you might understand what I'm talking about. For the meanwhile - I cannot announce anything as of yet!
