Handstand vs Planche

Should i master the handstand before learning the plance or i can learn them together?

I can already hold a straddle planche for a few seconds for about 3~5seconds depending on the day but i can hold a handstand for only 20~25seconds and can barely do 3 handstand pushups without losing balance(can do a LOT of those pushups if i have my feets on a wall). Should i stop the planche training and master the handstand before continuing my planche training?

Why would you do one or the other? Improve both

Jon! I have a question too , How many times a week should I do the handstand and planche training??

It depends on your actual level, there is no fixed schedule.
