I'm curious as to how many Chinese characters correspond to the pinyin "shi", such as 是 时 十 事 史 and so on. Is there an exact number of how many words (besides really archaic ones nobody uses) use this pronunciation?
Please see the pictures，the characters in the red box are common used. The link is https://zidian.911cha.com/pinyin_shi.html
Search: "shi" in pinyin (Mandarin) mode
(shi1) 濕, 師, 失, 屍, 施....
(shi2) 十, 石, 食, 識, 時....
(shi3) 駛, 始, 屎, 使, 史....
(shi4) 市, 式, 是, 事, 勢....
I often do this.
I use ibus pinyin input method to write Chinese. I set it to display 10 candidates each time. Just enter shi, then press tab until you run out of choices.
For shi I count 237 （23 x 10 + 7 in the last box). There are probably more, but these will be the most common ones.
For someone like me, who has problems with tones, this represents an enormous problem!!
