I thought 50% speed advantage would have a bigger effect. Some "fishy" estimate of the effect of a 50% speed advantage: 1. we know that 100%advantage gives an ELO plus of about 40 - 50 points; 2. extrapolating to 50% we expect a plus of 20 - 25 ELO points; 3. a player with an advantage of 20-25 ELO may expect a win of 53% - 54% So, you may (almost) ignore Shredder's speed advantage. >... >And, finally, I only gave MY PERSONAL opinion.
