No. Wrong conclusion. I did not think there was anything wrong with your pointing. Rather I suggested the hub should investigate, starting with your BUC transmit configuration level settings. If you want to help it may be useful to print out a copy of the 'options file' from each site and ask for explanation of all the differences. Apart from BUC power settings there are many other things that could be wrong but these are all matters for the hub to get right.
The hub need to see and measure your transmit signals on their hub spectrum analyser. I would not touch the dish unless the hub ask you to make an adjustment. e.g. elevation up 2 flats etc. They have precision test equipment and can easily see level changes in your transmit signal (in CW mode) and give you verbal guidance as you move the beam. Work slowly and systematically.
Polarisation:Calculate the angle using one of the dish pointing calculators
https://www.satsig.net/maps/ Add +3.5 deg for some Eutelsat satellites. Set the angle by starting with your LNB at the top or at the side and then apply the adjustment angle. Positive is clockwise while viewing towards the satellite. This
Iraq dish pointing calculator shows a picture of how your feed system should look. The calculator starts in Iraq but will work anywhere if you are not in Iraq. You need to input the name of your polarisation: vertical or horizontal.
If the polarisation scale is too tiny to read accurately try putting an inclinometer sideways across the BUC or LNB. Wrapping a paper strip round the throat may work. Mark and measure the circumferance C mm. The the distance needed is C x angle/360 mm. Rewrap the paper round the throat and use the pencil marks as a guide. Your hub may ask you to get under your feed arm and reach up to turn the feed in 1 deg increments till you are in the centre of the cross-pol null. Such adjustments need patience as it takes the hub 15 - 20 seconds to make each cross-pol measurement.
Azimuth:In azimuth (sideways) the trick is to loosen both nuts by say 2 turns and gently swing the dish many times against each nut alternately, measuring all the time and adjusting one nut till both degraded readings are exactly the same. Then wind in both nuts by exactly the same number of turns and flats, so as to centre the dish.
Elevation:In elevation (up-down), there is no backlash. Mark one flat on the nut with felt tip pen. Then wind right across the beam peak from a degraded measured value below to the same degraded value above. Then half count the turns and flats back to the centre.
Note that your receive beam has a broad rounded centre and it is not practical to try for the max value, you need to get exactly half way between the steeper sides of the beam. The transmit beam is narrower than the receive beam so any error (e.g. 0.5 dB) in the receive beam and your transmit pointing will be well off centre and your transmit quality will fail.
