Reading the spec I cannot follow how the implemented optimized version will
produce correct results?
E.g. [2 1]; -1 : according to spec the phase will be 5: -1 + 2*(2+1)
with the current optimized implementation it will be 4 (actually it produces
multiples of 4);
regarding the initial implementation: it should be checked that the sum of the
array components is >0 otherwise the loop will run forever
