Does top quark has scaled up variant?

Tommaso Dorigo writes in Quantum Diaries Survivor about The 450 GeV Quark That Wouldn't Go Away. What has been observed in CDF is indication for what looks like a scaled up copy of top quark with mass of 450 GeV. It is fun to test various new physics prediction of TGD. As I have told again and again, p-adic length scale hypothesis allows scaled up variants of quarks with masses coming as half octaves. The mass obtained by multiplying top quark mass 170 GeV with a factor 2^3/2 is 480 GeV and and 6 per cent higher than the rough experimental estimate.
