Regarding frequency, timing and amounts of payments from CS to MTR, I tried to grab a screen shot from the LFP video to save for reference. I couldn't easily figure out how to post a larger, clearer version here (although it's pretty clear if you watch the video in full-screen mode and then just pause it).
What you will see though, for the few months leading up to Apr 9, is that the deposits occurred on average every 2-3 days. Sometimes a couple of days in row, and sometimes several days apart. Amounts were typically in the $200 - $500 range, although there were several at $100 (a couple even lower) and one as large as $1000.
The last deposit before Apr 8 was on Apr 4 for $100.
Apr 8 there were the 2 deposits,as reported, for $400 at 9:47 and $100 at 2:58. There was another deposit of $300 on Apr 9 at 3:59.
Then....nothing for almost 2 weeks. Strange.
