I appreciate your post, however I think you need to do some research into proper risk management [meant in the nicest possible way].
The pip count is not the most relevant point of what you have just said or how I trade. The fact is that anyone trading in the way you suggest, ie 40/50% capital gone in a single trade isn’t going to make it as a professional trader as the unexpected always happens sooner or later. They are also going to become very familiar with the words ‘margin call’.
Risk management is the most important part of trading, second to none. The size of the account should never dictate that it is anymore or less risky to trade with. Any size, £100 or £10 billion should be properly managed.
The pip count isn’t the priority with regard to longevity, the leverage is. For a trader to be safe, they should trade with between 1-3% [depending on their trading style/system] per position, of the entire account balance [not equity] and therefore be in no risk of what you are suggesting above.
I hope that helps.
