bluff this river?

[waffle]

opponent is 49/15/1.8 over 200h.

raise continuation bet: 5%
call continuation bet: 52%
fold continuation bet: 48%
i know those don't add up to 100% but PAHud is a little buggy with this stat.

regardless of position, opponents, pot size, etc.
bet % of each street when it hasn't been bet yet: 52/68/47

i thought about popping the turn, but it seemed reckless?
