Good job ignoring the three other polls that came out today with No leads. ProRata has No up 54-33, Focus (??) has No up 40-37, and trusty Palmost Analysis has No up 52-37.
Focus is just the name of the radio station that published the poll. It was conducted by a small-time pollster called To The Point.
Here's how accurate each of the four pollsters were in their last 2015 election poll, to compare bias as well as general competency:
GPO (Yes +3.9): overestimated ND by +1.8, overestimated SYRIZA by +0.7, underestimated ANEL by -0.9
To The Point (No + 3.2): overestimated ND by +2.8, underestimated SYRIZA by -1.7, off by 1.0 or more with PASOK, ANEL, KKE, Potomi
ProRata (No + 21.0): overestimated Potami by +1.5, all other parties accurate within +/- 0.5
Palmos Analysis (No + 15.0): underestimated ND by -2.3, overestimated Potami by +1.5, underestimated ANEL by -0.8, all other parties accurate +/- 0.5
