c# - Background task memory usage WP8.1 -

according of link microsoft increases memory limit apps in windows phone 8.1 in 2gb device available background task 40mb memory. when trigger background task breakpoints in first string in run method see in windows phone developer powerfulness tools (8.1) task private bytes 30.73mb working set 31.27mb. memorymanager show me 35 mb in run method.

is mean can utilize 40-30=10mb needs in background task? is possible alter 30mb (switch off requirements in manifest)? how work 512mb devices available 16mb memory background task?

p.s. after reset of phone , reinstall application see 2 mb @ same string...
