Data in the link you posted shows only 1940 onwards. Here is the data compiled by Dr. B R Ambedkar from Army Archives, during the days leading upto partition:
% of Muslims in Indian Army
1914 -- 18.7%
1918 -- 17.4%
1919 -- 18.9%
1930 -- 22.6%
<b>Never more than 1/4th in the first three decades,</b> although in certain areas of the army, such as in infantry and cavalry, muslim %might have been as high at 30-35% by 1930, whereas in other areas as low as 5-10%.
Now, for the entire decade of 1930s, this religious-ethnic classification was concealed by the British for whatever unknown reasons. Dr. Ambedkar comments:
<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->It is one of the most intriguing things in the Military history of India that no information is available on this point after 1930. It is impossible to know what the proportion of the Muslims in the Indian Army at present is. There is no Government publication from which such information can be gathered. In the past, there was no dearth of publications giving this information. It is very surprising that they should have now disappeared, or if they do appear, that they should cease to contain this information. Not only is there no Government publication containing information on this point, but Government has refused to give any information on the point when asked by members of the Central Legislative Assembly.<!--QuoteEnd--><!--QuoteEEnd-->
Even this % of Muslims in British Army by the first decade of the 20th century -- ranging 18% on lower side and 27 on higher -- was actually an increase over what it earlier was! So, what was muslim %age in the 19th century?
Ambedkar quotes Chouduri who analyzed the religious composition of Army from the earliest days upto 1930:
<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->The pre-Mutiny army of Bengal was essentially a Brahmin and Kshalriya army of the Ganges basin.... on the eve of the Mutiny was mainly recruited from Oudh, North and South Bihar, especially the latter, principally Shahabad and Bhojpur, the Doab of the Ganges and Jumna and Rohilkhund. The soldiers recruited from these areas were mostly high-caste men. Brahmins of all denominations, Kshatriyas, Rajputs and Ahirs.
<span style='color:red'>The average proportion in which these classes were enrolled in a regiment was:
(1) Brahmin 7/24,
(2) Rajput 1/4,
(3) Inferior Hindu 1/6,
(4) Musalman 1/6,
(5) Punjabis 1/8. </span>
A single year and a single rebellion was, however, to change all this. The Mutiny, which broke out in 1857, blew up the old Bengal Army and brought into existence a Punjabized and barbarized army, resembling the Indian Army of today in broad lines and general proportions of its composition.

The other two regional armies - Madras and Bombay Native Armies, had even less Musalmans. Madras as much as 4-5% and Bombay 10-15% muslims. And even then Bangal Army was much larger than Madras and Bombay.
Musalmans, I repeat, were never a predomiant force of British Army, EVER. Only during WW-II, they might have gone upto 1/3 of total number, but that is the peak. Of course the Pakistani writers like the one you quoted, try to pose it differently.
In fact, I would guess INA of Netaji would have had a higher % of Muslims than British Army.
