I've been using CT for a while now.  Does it just get more and more expensive depending upon how many transactions you accumulate???  That is what it looks like now that my membership expired.  I would think it would be "Transactions per year", but looks like total transactions if I am reading it correctly?

So, if I have:


2018: 3000 transactions
2019: 2000 transactions

I have less transactions/imports in 2019, but my cost goes up because I have over 3,500 transactions total?  Is that correct?  Trying to figure out if I pay again and I doubt it if it is just going to keep going up and up in price each year even though I am using it the same way and transactions are going down. 

BTW - those are just example numbers, I've been using since 2016 and haven't paid much attention to how much I was spending to keep my subscription up.  According to my email: I last paid for 2 years in 2018 which expired last month.  I paid .382 ETH then, which equates to about $234USD and based upon archive.org. That was approximately the 2-year rate for Unlimited (https://web.archive.org/web/20171228150557/https://cointracking.info/pro.php), 0.029BTC = $239.82 USD. 

But - does that mean I pay based upon the total number of transactions... OR have I been doing it wrong?  Unlimited now is $600 for a single year, which seems excessive to me for only max 3k transactions / year for me.

Anyway... hopefully that explains well what I am asking.
