Landing gear down and segments?

Hi pprune!
A young soul here seeking clarification regarding aircraft performance...
When you depart on hot days, and when you keep your landing gear down to cool down, how do you do with the 2nd segment? Is that segment, during performance calculations, delayed? And if so, is that a separate calculation?
If i recall correctly, first segment ends when landing gear is fully retracted and all you have to take into consideration is a positive rate of climb (for a two engine)? In some airports obstacles are very close...My question is how those should be cleared when all you have to do is having a positive rate of climb (instead of, during 2nd segment, 2.4% gross and 1.6% net)?

I might just be young and stupid though...But i do believe in the power behind the question ''why?''.

Thanks!
