Gear ratios information about different models of Strida

So Strida MAS (16") is 18% faster than SX.
On my SX I can make up to 30km/h while in spec there is 24km/h

Strida MAS has 25 km/h in spec but maybe there should be 24 km/h +18% which is 28 km/h.

I can make 30 km/h on SX (24 in spec) so I should reach about 35 km/h on MAS which is really reasonable speed.

Has anybody tried it in real life ? How much faster is MAS than SX ?
