Thanks for taking a look at the spreadsheet. It's used to make it very transparent, who contributed how much hashing power to the whale while using the promo Code.

Let's make an example to answer your question:

• Max buys a 1 TH/s Bitcoin contract
  -> whale gains 0.03 TH/s when promo code is used
• Linda buys a 0.1 TH/s Bitcoin contract
  -> whale gains 0.003 TH/s when promo code is used

The whale got 0.033 TH/s mining power if you sum it up.

In this case Max would get 91% and Linda 9% voting power on bot votes.
That would be a fair distribution because Max contributed 91% of all hashrate.

Excactly this Information is put into the spreadsheet.

If anybody would get 100% voting power it would be easy exploitable.

I'll create a extra post with more detail Information, to make it more understandable.
