If their last block was a signalling block their 10% is included (so jumps to 94%) if their last block was not signalling they are not included so rate drops to 84%.
I think BTC.com said on twitter they should be signalling full time by end of this week. Assuming they do then is a dead cert for next period - otherwise will be very tight!
Looks like we are there!

BTC.com has signalled with all of their last 7 blocks!
So assuming no miner changes their mind will lockin around the Sat 12th June.
