Suggested change

	// Enforce the rate limit (independently on do_add_stake rate limits)
	// Enforce the rate limit (independent of do_add_stake rate limits)

Is this the expected behaviour? imo, one should be able to decrease without rate limit, but not increase until after the rate limit since the last change (increase or decrease)
