I love my Fenix 6X Sapphire. My only complaint is that it doesn’t recognize the distinction between hiking with a light daypack vs backpacking with a heavy (>30 lbs) backpack for purposes of counting calories. Seems like there should be an option to input estimated pack weight and have that influence the estimated number of calories burned.
The increased weight you're carrying is going to make you work harder increasing your HR which will burn more calories. There is no "x" amount of calories per "x" amount of weight carried.…

Quick test:
- 6 minutes walking with no additional weight
- 6 minutes…
They are relatively comparable. I’m going a little faster without that pack, and I had a little more elevation gain. My heart rates are comparable too. Should they be? Am I actually burning…
How thick do you have to be
IThey are very careful to couch what they say with conditions. There is a reason for that. I wonder what that could be.
Haha 
You don't understand the sentence:
When the conditions were given.
The pressure sensor is located in the main unit. This unit continuously measures the height while jumping. The speed of the jumper can be calculated by changing the height over time. If the system reports too high a SPEED below a defined trigger HEIGHT, it assumes an emergency.
Depending on the manufacturer, further CONDITIONS MUST be given.
When the conditions were given.
The main unit then sends an electrical pulse to the cutter, which is actuated by a pyrotechnic detonator.
This then INITIATES the OPENING mechanism of the reserve PARACHUTE.
THESE are the CONDITIONS which MUST BE GIVEN so that the OPENING of the reserve PARACHUTE be initiated
(Users manual) :
It activates the release unit when it detects a rate of descent higher than approx. 78 mph (35 m/s) at an altitude of approx. 750 feet (approx. 225meters) above ground level (AGL). In the event of a cutaway CYPRES will operate down to approx. 130 feet above ground level. Below approx. 130 feet (approx. 40 meters) above ground level open- ing is no longer useful. For this reason, CYPRES ceases operation below approximately 130 feet above ground level.
——
In ALL other CONDITIONS it should NOT activate. If it does, it can kill you.
Ideally, you will pay a lot of money to purchase and maintain it, but hopefully it’s never needed.
Certain life-threatening CONDITIONS must BE GIVEN for the system that it activates itself.
You usually fall at up to 200 km / h (50 m / s). When CYPRES is activated you have 4 seconds until you hit the ground. So if it hadn't worked once in the more than 4000 rescues, it would have meant death.
Man how hard is that ?
It has failed in other situations where the results wernt critia
NO ! Where did you read that ?
Since 10th January 1991 no CYPRES failed to activate when the conditions were given. Therefore CYPRES showed a level of reliability within the reach of 100% at that time.
Do you mean this text? you simply do not understand it. If you want to understand how it works, read the German wiki article completely.

So ist beispielsweise bis heute kein Fall bekannt, bei dem ein richtig bedientes System vom Typ Cypres im Notfall nicht ausgelöst hätte.
translation :
For example, no case is known to date in which a properly operated system of the Cypres type would not have triggered in an emergency.
From the Company 25th celebration :
CYPRES has been along on 120 million jumps; in all that time, no CYPRES has ever failed to activate, and no CYPRES has ever failed to sever the reserve loop.
Either its 100% or it isnt, you cant sit on both sides of the fence.
Is everything clear now?
Can we all go back in topic please?
with pleasure 
sorry for that!
