Hello Everyone!

What could be the reason for getting a fat and foamy shot? seconds 12-16 the shot tail is bigger than what I have seen on videos. What could be the reason for it?

My workflow is: 

1. Grind at 5 clics on my Encore ESP (i need to replace shims)
2. run an empty shot to preheat my PF and machine
3. dry the PF
4. pass the coffe and use a needle WDT from Normcore (sometimes i give it a few taps, i am not sure if this helps or not, but anyways this issue is still going on independently of tapping)
5. use a Normcore tamper which has a resistance, tamp twice 
6. set up my cup, scale and put the PF on the machine
7. use manual mode, clicking the button up to 10 seconds so there is some preinfussion
8. stop the pump at 35ml so it lands on 36-37.5ml

The flavours I am getting are: The acidity is nice (no longer tastes like a lemon), it dries the mouth somewhat and its like almost a pleasant dark chocolate. There is no sweetness at all. The body has a syrupy consistency which I like, and the aroma is good. 

  
The coffee I am using is called Lupo from Mexico (Xicotepec Puebla) it is single origin arabica, medium roasted, washed. It says the notes are chocolate, caramel, hazelnut, honey, vanilla and fruit. I dont have the roasting date but its not a stale or super fresh coffee

  
Thank you for your time
