الجواب حامدا و مصلیا
Due to a Shar’I excuse or a physical weakness if a male or a female performs less number of Raka’at of Traweeh instead of 20, his/her action although is a cause of reward and Sawab but Sunnat will not be accomplished by this. Sunnat will be accomplished only by performing 20 Raka’ats and it is necessary to be diligent on it.
Allah knows best.
