Filter Conditions in swtich() function

I am creating a new column in one of my tables

my dimension table has a one to many relationship with my fact table on a column called Machine ID

What I am trying to do is compare the individual vehicle 75th percentile kilometre values with their respective group 75th percentile kilometre value

Depending on the value of the group 75th percentile value and the individual 75th percentile value, the individual vehicle should be assigned to one of four categories:
* <= 100km
* > 100km and <= 150km
* > 150km and <= 200km 
> 200km

my DAX runs without error, except it only categories the vehicles into the first category (<= 100km)

The DAX that I am using to do this is here:

DistanceCategory =
VAR VehicleType = SELECTEDVALUE('Dimension'[Vehicle Type])
VAR Vehicle = SELECTEDVALUE('Dimension'[Vehicle ID])

-- Group 75th percentile value
VAR GroupPercentile =
PERCENTILEX.INC(
FILTER(
FACT,
LOOKUPVALUE(
'Dimension'[Vehicle Type],
'Dimension'[Machine ID],
FACT[Machine ID]
) = VehicleType
),
FACT[Kilometres],
0.75 -- 75th percentile for the group
)

-- Individual vehicle 75th percentile value
VAR VehiclePercentile =
PERCENTILEX.INC(
FILTER(
FACT,
LOOKUPVALUE(
'Dimension'[Vehicle Type],
'Dimension'[Machine ID],
FACT[Machine ID]
) = VehicleType &&
LOOKUPVALUE(
'Dimension'[Vehicle ID],
'Dimension'[Machine ID],
FACT[Machine ID]
) = Vehicle
),
FACT[Kilometres],
0.75 -- 75th percentile for the individual vehicle
)

-- Categorize based on group and individual vehicle 75th percentile
RETURN
SWITCH(
TRUE(),
GroupPercentile <= 100 && VehiclePercentile <= 100,
"<= 100km",
GroupPercentile > 100 && GroupPercentile <= 150 &&
VehiclePercentile > 100 && VehiclePercentile <= 150,
"> 100km && <= 150km",
GroupPercentile > 150 && GroupPercentile <= 200 &&
VehiclePercentile > 150 && VehiclePercentile <= 200,
"> 150km && <= 200km",
GroupPercentile > 200 && VehiclePercentile > 200,
"> 200km",
BLANK()
)
