Nice table. BTW Rizful and Megalith LSP use the exact same code to determine opening fees. It's dependent on the prevailing chain fees. So you saw 19,878 and 20,282, which makes sense, probably there was a few minutes delay between these two prices, that shows the difference.... but if you got the prices from Rizful and Megalith LSP at the exact same moment, they should be the same...;)

Also. Wanted to note. Megalith LSP and Rizful both guarantee a 3 month duration, unless the user goes offline for more than 30 days..... but also, possibly different from other LSPs, that duration is EXTENDED INDEFINITELY if you actually USE the channel -- i.e. you send sats or someone else sends sats. If your node stays online (which it will perfectly if you use a cloud service like Rizful or Alby Hub), and if you send or receive sats at least once or twice per month, you should see that your channel NEVER closes.
