Transact SQL :: Comparing 2 Records / Multiple Instances In The Same Table For A Specific Combination?

I have a problem where I have 2 compare 2 records from the same table. This part looks easy but the problem is for a User there can be multiple records and I have 2 compare each record with its previous instance based on the timestamp. Not only I have to compare I have to perform some analysis. Below is the Table script and sample output.

Production database contains the following tables (simplified for example: constraints ignored, etc.) associated with a racing video game’s server.

-- A player of our game

-- Table greater than 10 million rows

CREATE
TABLE [dbo].[User]
(
[UserId]              
[bigint] NOT
NULL  
,[country]             
[int] NULL   
-- User’s home country
,[name]                
[nvarchar](15)
NULL  -- User’s displayable name (‘John’, ‘Bill’)
,[subscriptionTier]    
[int] NULL
)
-- 0 == free, 1 == paid, for instance

Assume that rows get written into the event tables at a rate of 1,000 a minute,are never updated once written and currently are only read on a replica/reporting server.

Question Background: Write up a single query that would return the following: List of users and whose “TotalMoneyEarned” value ever grew (between logon events) at a rate of more than 1,000 per minute (we’d consider these suspicious and flag them for later investigation). 

For instance, if the sample data were:

-- example of [Events.UserLogon] data  -- not the query output we want

EventId     UserId               TotalMoneyEarned LogonDate
----------- -------------------- ---------------- -----------------------
1           1               1000             2010-10-16 00:19:56.460
2           1               1500             2010-10-16 00:20:56.460
3           1               3000             2010-10-16 00:21:56.460
4           1               10000            2010-10-16 00:29:56.460

Event 1 is okay because there’s nothing to compare it against

Event 2 is okay because the TotalMoneyEarned only grew 500 in a minute

Event 3 should be flagged, as the value grew 1500 in a minute

Event 4 is okay, as it grew 7,000 in 8 minutes (< 1000 per minute)

Query Output (your query should return data in a format like this):

User      Flagged Logon Time    Rate Since Last Logon (money/minute)
John      2010-10-16 00:21:56   1500
Dave      2010-10-16 00:30:50   3200
Bill      2010-10-16 00:35:23   1000

It is likely that you will need to create sample data for both the User and [Events.Logon] tables.  We are looking for a single query that returns data like what is represented in Query Output.
