Hot and Neutral bus question

[LarMoeCur]

I'm doing a 50A B2B Kal Clone. I think I'm wiring the buses correctly but want to ask to make sure. Looking at Pictures of Kal's builds the buses have three to four slots taken and jumpers connecting them. I'm follow in the wiring diagrams and have way more slots filled. Here's my break down:

Hot Bus
1. 120v Blue light - jumped to 2 and 8.
2. Boil element switch - jumped to 3.
3. HLT Element Switch - jumed to 4.
4. PIDs & Timer (Slot 9) - Jumped to 5.
5. Pumps switchs and lights.
6. blank
7. blank
8. 7a fuse - jumped to 1.

Neutral bus.
1. 120V blue light - jumped to 2 and 8.
2. Z input from Main plug - jumped to 1 and 3.
3. 30a relay - jumped to 4.
4. 30a relay - jumped to 5.
5. PIDs and Timer (slot 10) - jumped to 6.
6. Pumps linked to switchs and lights.
7. blank
8. 50a 2 pole relay - jumped to 1.

My question is that I have way more slots filled are some of these paired up? or all run single to the bus? It also seems like a lot of jumpers. The wiring looks correct to me but I am by no means an expert.

Thank in advance for the help!

You can use one of these to avoid jumpers

I knew there was a better way than jumpers. One hot in makes them all hot. Way easier than jumping...I may swap them out when I get back in port.
