FADC on pad is actually really easy. Only mash and charge things like Chun Li's legs, Juri's projectiles and Fuertes Quesadilla might prove a challenge. Which probably requires either button config change or change in how you hold the pad.
Posting the
C-Ryod 3S hit confirm tutorial video again 
.
cr.LP into cr.MK is not a link and what you did was not a hit confirm. More about that later on.
Usually the force standing attribute is a testing thing. You put the dummy on crouch and see how it reacts on hit. You can do that even right now with USFIV.
Combo testing is just simply trying to see what links into each other. There is a lot of testing to be done without frame data. You go through each move with a 1-2, i.e. Chun Li as an examle: cr.LP into st.MP, cr.LP into cr.MK, and so on with each button that would make sense.
Buttons with long animations like st.HP or st.HK for example do not make sense to use mid combo, because they can't be cancelled and lead to nothing else.
If you do not know frame data and need to know whether you are in advantage or not. You can use dummy record function, use the button you want you want to test and press and hold up. You block the attack and hold up too, the timing difference of the jumps will tell you.
After knowing what can combo, you try and see what is practical.
In fighting games nobody is going to try and confirm off each button, because the time period is too short. This is why you use hit confirms.
Hit confirms are a sequence of buttons that combo into each other and increases the time you can react and are part of your BnB reportoire. As in the posted tutorial video you only watch for the first attack to hit. Because if your first attack hits your other attacks are guaranteed to hit too. In a sense you can call a Hit Confirm a choreography.
SFV Chun Li's BnB is st./cr.LP, st.MP, cr.MK into legs.
Whether you can confirm on the second part which is the st.MP or not is another question and needs to be tested with a dummy put on random guard. But in general case you check the first hit, whether you hit or not is irrelevant you still follow up with st.MP. Having executed cr.LP, st.MP should have given you enough time to react whether you managed to get a hit or not. If you manged to get a hit you continue into cr.MK into legs. If your first attack got blocked then you need to decide what to do next after the st.MP, which gives you frame advantage.
Now as mentioned in the frame data post there are different types of Hit Confirms.
- Slow attacks that leaves you enough time to react
- A Block String which is 100% safe on block
- A Frame Trap that can be broken through with armor or invincibility
Ryu f.HP or b.HK would be type 1.
Cammy doing cr.LP chain cancelling into cr.LP and special cancel into Spiral Arrow would be type 2.
The above mentioned Chun Li BnB is type 3.
If you want to try the USFIV equivalent out here are examples:
Important note: In USFIV you cannot special cancel chain cancelled normals. Chain cancels are normals cancelling into itself, which is usually only possible for lights.
- Ryu: f.HP into DP or advanced f.HP, cr.HP, DP
- Ken: cr.LP chain cancel into cr.LP, cr.LP into HP.DP. Possibly also Chun: cr.LK chain cancel cr.LK, cr.LK into EX Legs.
- Ryu: cr.MP, cr.MP, cr.HK
I hope this helps you understand Hit Confirms a little bit better.
Whether I am going to train with you or not is probably more of a question of connection quality, since I'm from the EU. If it is not laggy then sure.
