My screed floor looks flat, but its certainly not.

Comparing the high and low points, there is upto 10mm difference in
height.

I was originally going to put some self leveling down, but my
neighbour (who is a tiler) talked me out of it. Instead, he said that
I could vary the thickness of the adhesive to level the floor.

Is this suggestion OK? If so, whats the maximum thickness of adhesive
that I can lay?

The stuff I'm using says it can manage up to 10mm in small areas.
However, I haven't gone anywhere near that thick.

You can take up quite a bit of irregularity with flooring adhesive that you
mix from dry powder, because its cement based. However, 10mm sounds a lot
unless its just the odd void that you could splodge in more adhesive.
If its a slope or change of level of 10mm between two side of the room I
would suggest this could be quite tricky for a DIYer to compensate for esp.
if you haven't laid floor tiles before.

This morning I have layed 24 of 100 tiles, and was pleased with the
results.. In laying them, I have realised how un-even the floor is,
but feel that I am doing a good job at leveling it with the adhesive,
by putting it on the floor AND 'buttering' the back of the tiles where
needed.

Its taking time, but I am getting there.. I would say that 70% of the
floor is at the correct level and the other 30% are 'patches' where
the floor us no more that 10mm lower (probably a lot less).

In one corner I am having to build up the level a lot more than
anywhere else, but it seems to be going OK.

I guess the true test will be when its finished and I start walking on
it.. If the tiles start to shift, then I guess I am in trouble.

I don't know if this will make it stronger, but I am raking out all of
hte adhesive from between the tiles, so that I can get a good load of
grout between then when I grout the tiles at the end...

My fingers are crossed!

That is a very good idea. Powder grout will actially glue them down as
well, as will huge quantities of PVA poured down the cracks Useful
technique if any tiles break loose.

A tle that is fully supported at its edges will not rock and break
loose. Grout can do that.
