Oxygen Tank Useless / Not Balanced for 1 sec/1 turn

[RedPine91]

Bug

Oxygen Tank requires 10 seconds to use, and grants no noticeable increase in stamina gain. This is likely due to the 1 sec/1 turn rebalance which adjusted turn times and inflated the stamina pool.

Steps To Reproduce

1. Run until winded (a single red ":" on the stamina bar)
2. Look at the in game time.
3. Use an oxygen tank.
4. Watch as you waste 10 seconds to refill less than a single stamina bar.

Expected behavior

IIRC, before the 1 sec/1 turn change, oxygen tanks could be used to refill stamina while you ran from enemies. In any case, the item is currently useless.

Possible Fix

Increase the amount of stamina regained. Current time to use is fine if the stamina regained is very significant, otherwise the time to use should be drastically reduced.

Versions and configuration

Experimental 9272, windows 10.

This is a strange use of oxygen tanks anyway and should just be removed. Hypoxia isn't why you run out of stamina.

Exercise performance is determined by oxygen supply to working muscles and vital organs

In studies performed near sea level in healthy subjects, as well as in patients with PH, maximal performance during progressive ramp exercise and endurance of submaximal constant-load exercise were substantially enhanced by breathing oxygen-enriched air

http://rc.rcjournal.com/content/57/7/1154 This article is mostly related to COPD, but contains something in general too

During exercise, demand for oxygen by working muscle increases in proportion to the level of work performed.10 This results in a higher cardiopulmonary demand to deliver necessary oxygen to active tissues.

Work rates above a level for a given individual are accompanied by relatively inefficient anaerobic processes; termination of exercise occurs when these processes are exhausted. For normal individuals the delivery of oxygen (cardiac output × arterial oxygen content) to tissues is regulated by changing cardiac output to meet the imposed metabolic demand of exercise; pulmonary ventilation is increased to prevent decreases in arterial oxygen content.

I disagree with Erk. Seeing as stamina drain has been increased significantly in recent builds and also considering how deadly it is I think the use of oxygen tanks is a nice counterbalance. Maybe, instead of an instant boost to stamina, just having it end or even prevent the winded effect on use and perhaps apply an 'Oxygenated' effect that slightly increases stamina regeneration for a short time.

[I-am-Erk]

From that paper, you see my argument displayed eloquently: the effect of hyperoxygenation on performance in healthy individuals is measurable, but miniscule. The current benefit of the oxygen tank roughly represents how much difference it actually makes. You'll note that the authors of the paper rather conspicuously tall about their results being "significant" but don't talk about the magnitude of the difference when they can possibly avoid it. I don't think there's a lot of value to simulating that

You do not remember correctly, the oxygen tank does not have this effect. What it does do is cure the, "winded" effect immediately, which is also a debatable use.

this is a stupid fix, just remove the o2 tank out of the game.
