Appendix D Growth of isobutane

In this appendix, we demonstrate that for the growth of isobutane, all trial segments have to be inserted simultaneously. 

In schemes in which bi and b2 are not inserted simultaneously it is assumed that 

It is important to note that this is assumption is only valid if 

Because of the dependence of the second term on l.h.s. on b i this equation does not hold in general.
