Junção T-SQL para obter registros de início e parada não acoplados e não acoplados

Eu tenho uma tabela mal projetada que eu não criei e não posso consertar / alterar porque um aplicativo de terceiros BlackBerry que escreve para ele. A carne é que há um registro de início e um registro de parada para rastrear eventos com nenhuma conexão ou validação de que haja uma correspondência. O aplicativo blackberry não faz nada para amarrar esses registros juntos. Eu tentei criar uma junção em si mesmo e criar tabelas temporárias com o início e um com o fim para o total externo se juntar a eles. O problema é que eu tenho entradas duplicadas onde a entrada deve ser marcada como não tendo nenhum mate. Os dados existentes possuem linhas sem nenhum posicionamento nos registros inicial e final. Eu procurei por respostas e encontrei algumas respostas próximas que me levaram até aqui. Eu sei que é um longo post, desculpe por isso.

Existe umsolteiro tabela que surpreendentemente tem uma chave primária. Não há tabela de pivô / interseção. Estrutura é

ID (int PK)
activityType varchar
beginEnd varchar ('begin' or 'end')
businessKey varchar nullable
date DATETIME
technician varchar

As colunas a seguir também estão na tabela, mas são anuláveis e não são importantes para a consulta.

dateSubmitted DATETIME
gpsLatitude float
gpsLongitude float
note varchar
odometer int

A consulta que tenho agora que ainda deixa dupes: Mostrando e classificação ID e EndID são apenas para depuração

DECLARE @DateFrom DATETIME
DECLARE @DateTo DATETIME
SET @DateFrom='20101101'
SET @DateTo='20101102'
DECLARE @Incomplete VARCHAR(15)
SET @Incomplete = 'Incomplete'

DECLARE @StartEvents TABLE
(
[id] [numeric](19, 0) NOT NULL,
[activityType] [varchar](255) NOT NULL,

[technician] [varchar](255) NOT NULL
)

INSERT     @StartEvents
       ([ID],[activityType],[beginEnd],[businessKey],[date],[dateSubmitted],[gpsLatitude]
            ,[gpsLongitude],[note],[odometer],[technician])
SELECT      *
FROM        dbo.TimeEntry
WHERE 
[date] between @DateFrom AND @DateTo
AND beginEnd = 'Begin'
--AND [technician] = 'FRED'
