a Riddle to be answered by Peerplays (or someone with good mathematics skills) or tokendata.io

A Riddle which has been Perplexing me all evening !

If I invested

1.2 ETH into the Peerplays Crowdsale (worth approx $100) at the time (09.05.17) and received 19.943 ppy tokens in exchange (30.05.17) & ppy tokens are currently valued at $5.37 according to tokendata.io but were worth $0.526 on ICO release,

why would I have not made a 10.2x ROI as tokendata.io suggests ?
Is their data incorrect, have I done my sums wrong or were my tokens mis-allocated ?

Workings Out

I worked out that if the tokendata is correct, I should have received approx 190 tokens instead of the 19.943 which means my tokens would now be worth around $1,020 instead of $107 (which is about the same as they were worth at ICO) except 1.2 ETH would have now been worth $326.79 at today's price estimate according to worldcoinindex.

Figures on Peerplays extracted from tokendata below

capital raised $500,000.00 date May 2017 ICO value $0.526 current value $5.370 ROI 10.20x

if anyone can shed some light on this I would be very grateful because I can't seem to get a reliable figure on ppy token values and was surprised to see tokendata's figures, although I don't know where or how they obtained them.
