Using the golden ratio here is exponential growth - it is not a
"compromise between exponential and arithmetical growth".

You could argue that it is a convenient way to get an exponential growth
that is lower than powers of 2 while still being possible to calculate
with easy integer arithmetic.  And while there are some algorithms that
have best amortized performance when using Fibonacci numbers (such as
the Fibonacci heap for priority queues - or perhaps when choosing the
size of lumps for malloc to request from the OS memory manager), it is a
very big stretch to generalise that to saying the Golden Ratio is /the/
best choice for searching.

In this case, powers of two is clearly the best choice for searching
since we are merely looking for an indication of the scale of the value,
using a simple and quick program.
