There are tactical issues with this method. It is in your interests to
not vote for someone who is already going to be elected. It is also in
the
interests of a party to try to "vote manage". If they can evenly split
their
vote, then they can get more candidates.
One of the big benefits of STV/approval/range in the single seat case
is not
just that they elect a candidate better than plurality, it is that they
allow
better voter expression. Even if someone loses an election, they could
still be getting a better election/election share of the vote, keeping
their
supporters interested and also demonstrating to the incumbent a possible
demographic to appeal to.
Tactical voting works against that. If people tactical vote, then they
get
no method to express their actual desired.

I assume that should be:
A: 25, B: 100, C: 1, D: 75
?

Another method that might be a good idea would be to limit the total
number
of points that can be given based on multiple candidates.
For example, in PAV, the max I can cast is:
1: 1 vote
2: 1.3333 votes
3: 1.5333 votes
4: 1.6762 votes
So switching to range, it would be limits:
1: 100
2: 133
3: 153
4: 168
You would vote giving each candidate a score. However, the above limits
would be in effect based on how many candidates are being considered,
so you
don't overvote.
In your election, a ballot of ( A: 25, B: 100, C: 1, D: 75 ) would
become:
AB: 100+25 = 125 => 125
AC: 25+1 = 26 => 26
AD: 25+75 = 100 => 100
BC: 100+1 = 101 => 101
BD: 100+75 = 175 => 133 ( limited to 133 as 2 candidates )
CD: 1+75 = 76 => 76
In effect, your approval for an outcome is just the sum of your approval
for each of the individual candidates elected. However, there is a
limit
to prevent any one vote from becoming to strong.
This still collapses to PAV if all the voters vote 100 and 0 for every
candidate.

For larger elections, it would probably be better to use the sequential
method. Otherwise, there will be incentive to use computers for
counting/
recording the votes, which increases the potential for corruption of
election officials.
